Description
Technical Field
[0001] This invention relates to the field of automated printing technology, and in particular to a method and apparatus for generating custom forms for printing. Background Technology
[0002] Fixed-value printing is the operation of outputting pre-set fixed parameters from equipment or systems as fixed values in paper or electronic document form. It is commonly used in industrial control, power protection, and the debugging and routine maintenance of electrical equipment. Generating a table is a crucial step in fixed-value printing. Existing tables typically have fixed rows and columns, making it impossible to merge cells during use, unsuitable for diverse table display needs, and requiring column widths to be set before use; they do not automatically adjust width based on table content. Furthermore, inconsistencies exist between print previews and actual print results across different platforms, and previews may not align correctly. Summary of the Invention

[0008] According to some embodiments of the present invention, determining the number of tenth characters based on the top width includes: Based on the target row that is not the first row, if the number of columns in the target row is less than the previous row in the target table, the tenth character corresponding to the end of each column in the previous row is replaced with the eighth character; or, if the number of columns in the target row is greater than the previous row in the target table, the top left boundary character is replaced with the seventh character.
[0009] When the growth attribute of the target table is horizontal growth, for each row cell, if the content width of the cell content is less than or equal to the preset column width, the number of the tenth characters is determined based on the preset column width; or, if the content width is greater than the preset column width, the number of the tenth characters is determined based on the content width. The growth attribute is used to characterize the expansion display direction after the content width exceeds the preset column width. When the growth attribute of the target table is vertical growth, the number of the tenth character is determined according to the preset column width.
[0010] According to some embodiments of the present invention, determining the top right boundary character includes: If the target cell is not located in the last column of the target row, set the top right border character to empty; When the target cell is located in the last column of the target row, and the target row is the first row of the target table or is in single-row mode, the third character is determined as the top right boundary character, wherein the third character is used to represent the upper right corner of the table; When the target cell is located in the last column of the target row, and the target row is not the first row of the target table or is in a multi-row mode, when the target cell has a top border, the sixth character is determined as the top right boundary character; or, when the target cell has no top border, the eleventh character is determined as the top right boundary character.
[0011] According to some embodiments of the present invention, serializing the left-middle character, cell content, and right-middle character of each row cell into an intermediate string includes: When the middle left character and the middle right character are configured to be hidden, the middle left character and the middle right character are set to empty; otherwise, they are set to the eleventh character. Determine the number of characters to fill and the content text of the target cell, and divide the content text into multiple lines of sub-text; When the target cell is in multi-line mode, the cell content is constructed based on the multi-line sequence content, wherein the sequence content includes a fill string, the subtext, the fill string and a newline character in sequence, the last line of the sequence content does not include the newline character, the fill string includes multiple fill characters, and the number of fill characters in each fill string is half the number of fill characters; When the target cell is in single-row mode, the cell content is constructed based on the fill string, the content text, and the fill string.
[0012] According to some embodiments of the present invention, when the target row is located in the last row of the target table, the bottom string is obtained by serializing the bottom left character, the cell content, and the bottom right character, including: The second character is determined as the bottom left character of the first row cell, wherein the second character is used to represent the bottom left corner of the table; Based on any non-first row cell, if the bottom left character is configured to be hidden, the tenth character is determined to be the bottom left character; otherwise, the eighth character is determined to be the bottom left character. The fourth character is determined as the bottom right character of the last row cell, and the bottom right characters of the remaining row cells are set to empty, wherein the fourth character is used to represent the bottom right corner of the table; The bottom width of each row cell is determined based on the number of fill characters.
[0013] According to some embodiments of the present invention, generating a preview table of the target table based on the row printing information of all the target tables includes: Search for multiple optional fonts, wherein the optional fonts include multiple categories of available characters with different language types; When a target font is found, the fill character is set to a space. The width of the space between the fill characters of different types of available characters is determined according to a preset width ratio, wherein the multiple types of available characters of the target font are of equal width. If the target font cannot be found, the padding character is identified as a tab character, and the width of the tab character is set to a unit pixel width. The number of fill characters is determined based on the width of the row cell, the width of the cell content, and the width ratio.

The method includes: traversing a target table row by row from top to bottom, determining the currently traversed row as the target row, wherein the target row includes multiple row cells; based on any one of the row cells, determining a top left boundary character, determining the top width of the row cell, determining the number of tenth characters based on the top width, determining a top right boundary character, determining a middle left character and a middle right character, wherein the tenth character is used to represent the top or bottom side of the table, excluding the four corners of the cell; and combining the top left boundary character, the multiple tenth characters, and the...

[0022] The following is based on the appendix Figure 1 The illustrated table and the table of correspondences for various characters shown in Table 1 further illustrate the technical solution of the embodiments of the present invention.
[0023]
[0024] Table 1: Character Lookup Table Reference Figure 2 , Figure 2 The flowchart illustrates a method for generating a custom table for printing, as provided in an embodiment of the present invention. This method includes, but is not limited to, the following steps: S11 traverses the target table row by row from top to bottom, and determines the currently traversed row as the target row, where the target row includes multiple rows of cells.
[0025] It should be noted that after obtaining the target table, this embodiment traverses the target table row by row, and each row is determined as the target row to execute step S12. In the field of fixed value printing, each row of the table includes at least two rows of cells.
[0026] S12, based on any row cell, determine the top left boundary character, determine the top width of the row cell, determine the number of tenth characters based on the top width, determine the top right boundary character, determine the middle left character and the middle right character, where the tenth character is used to represent the top or bottom edge of the table that is not at the four corners of the cell.
[0027] It should be noted that, as Figure 1 As shown, in this embodiment, each row is broken down into a top string, a middle string, and a bottom string. In actual use, each table can set the top, bottom, left, and right borders of the cells to show or hide them. By hiding the borders, the cells of multiple rows or columns can be merged and displayed. In this embodiment, in step S12, the corresponding characters of each row cell are determined one by one. Finally, the strings of each row cell are serialized to obtain the string corresponding to the entire row.
[0028] It should be noted that the top left margin character is used to represent the left boundary of the row cell. For example, it can be the first, second, fifth, or eleventh character as shown in Table 1, depending on the position of the row cell and the display / hide attribute of the surrounding cells. The top right margin character is similar, and can be the third, fourth, sixth, or eleventh character as shown in Table 1.
[0029] It should be noted that, as shown in Table 1, the tenth character is "─", and therefore can be used as the top border. In this embodiment, the top width is determined based on the cell content of the row cell, and the number of characters in the cell content corresponds to the number of the tenth character, thereby realizing that the width of the row cell is dynamically adjusted according to the content.
[0030] It should be noted that, as Figure 1 As shown, the left-middle character, cell content, and right-middle character of each row cell are used to determine the middle string. Since the width of the top string is determined based on the cell content, it can be ensured that the middle string and the top string can be aligned. The left-middle character and the right-middle character are also determined based on the position of the row cell and the display / hide attribute of the surrounding cells. No further restrictions are made here. For example, they can be the fifth character, the eleventh character, etc. in Table 1.
[0031] S13 serializes the top left boundary character, multiple tenth characters, and top right boundary character of each row cell into a top string, and serializes the middle left character, cell content, and middle right character of each row cell into a middle string.
[0032] It should be noted that after obtaining the top left boundary character, multiple tenth characters, and top right boundary character of each row cell according to step S12, the top characters are serialized in sequence to obtain the top string, and the corresponding middle string is obtained similarly. Through the above operations, the top and middle of the target row can be represented in the form of strings, and it can be ensured that the printed content is aligned.
[0033] S14, determine the bottom string of the target row, where the bottom string is empty if the target row is not the last row of the target table, or the bottom string is obtained by serializing the bottom left character, cell content and bottom right character if the target row is the last row of the target table.
[0034] It should be noted that, since the top string of the next line overlaps with the bottom string of the previous line, in this embodiment only the bottom string of the last line includes the corresponding bottom left character, cell content, and bottom right character, while the bottom strings of other lines are set to empty.
[0035] S15: Construct the row printing information of the target row based on the top string, middle string and bottom string, and generate a preview table of the target table based on the row printing information of the entire target table.
[0036] It should be noted that in this embodiment, the top string, middle string, and bottom string are stored in a cache as row printing information. The target row is printed using this row printing information, and multiple rows of printing information together form the printing information for the target table. During printing, the top string is printed first, completing the top printing of a row; then the middle string is printed, completing the middle printing of a row; and finally, the bottom string of the last row is printed, completing the printing of the target table. During previewing, a preview table is generated row by row based on the row printing information, ensuring that the preview and printed content and format are identical.
[0037] In another embodiment, in step S12, determining the top left boundary character specifically includes, but is not limited to, the following steps: S21: Determine the target cell as the currently traversed row cell, and determine the display mode of the target row. The display mode can be either single-row mode or multi-row mode. S22, when the target row is the first row of the target table or is in single-row mode, the first character is determined as the top left border character of the target cell in the first column. In the target cells that are not in the first column, the seventh character is determined as the top left border character of the target cell with a left border, and the eleventh character is determined as the top left border character of the target cell without a left border. The first character is used to represent the top left corner of the table, the seventh character is used to represent the right side of the table that is not a left or right border, and the eleventh character is used to represent the left or right side of the table that is not a four-corner of the cell. S23, when the target row is not the first row of the target table or is in multi-row mode, for the target cell in the first column, the fifth character is determined as the top left boundary character of the target cell with a top border, and the eleventh character is determined as the top left boundary character of the target cell without a top border. For the target cell that is not in the first column, the top left boundary character of the target cell is determined based on the cell above it. Here, the fifth character is used to represent the left side of the table that is not the top or bottom boundary, and the cell above it is the cell located in the row above the target cell and in the same column.
[0038] It should be noted that, for ease of explanation of the technical solution, this embodiment determines the currently traversed row cell as the target cell. This embodiment serializes the top string and determines the top left boundary character based on its positional relationship with surrounding cells and the display mode. The display modes in this embodiment include single-line mode and multi-line mode. Single-line mode displays a single line of content within the cell, while multi-line mode displays multiple lines of content.
[0039] It should be noted that in step S22, the target row is either the first row or a single row of the table. When the target cell is the first column, it is located at the top left corner of the target table, and the top left border character is the first character shown in Table 1. When the target cell is not the first column, it is necessary to determine whether the target cell has a left border. If there is no left border (e.g., the left border is set to hidden), the seventh character shown in Table 1 is determined as the top left border character. If there is a left border, the eleventh character is used as the top left border character.
[0040] It should be noted that if the target row is not the first row or in single-row mode, the cell above the target cell, or the cell above it, needs to be merged with the cell above it by hiding the top border. In step S23, when the target cell is in the first column and has a top border, the fifth character shown in Table 1 is used as the top left border character; when there is no top border, the eleventh character is used as the top left border character. When the target cell is not in the first column, this target cell has neither horizontal nor vertical borders and is not printed in a single row. The top left border character of the target cell is determined by judging whether the cell above it and the target cell have left borders.
[0041] In another embodiment, in step S23, the top left boundary character of the target cell is determined based on the cell above, which specifically includes, but is not limited to, the following steps: S231, When both the upper cell and the target cell have left borders, the ninth character is determined as the top left border character, where the ninth character is used to represent the interior of the table that is not bounded by the top, bottom, left, or right borders; S232, when the cell above has no left border and the target cell has a left border, the seventh character is determined as the top left border character; S233, when the cell above has a left border and the target cell does not have a left border, the eighth character is determined as the top left border character, where the eighth character is used to represent the bottom of the table that is not a left or right border; S234, when neither the cell above nor the target cell has a left border, the tenth character is determined as the top left border character.
[0042] It should be noted that in step S23, when the target cell is not located in the first column, a comprehensive judgment needs to be made based on the cells above it. In step S231, when both the target cell and the cell above it have left borders, the ninth character shown in Table 1 is used as the top left border character. The ninth character indicates that the target cell is located inside the table and is not at the top, bottom, left, or right borders. The ninth character provides borders for both the target cell and the cell above it.
[0043] In step S232, when the upper cell has no left border and the target cell has a left border, the upper cell is merged with its adjacent row cells. At this time, the seventh character is used as the top left border character of the target cell to represent the top of the table.
[0044] In step S233, when the upper cell has a left border and the target cell does not have a left border, the target cell needs to be merged with the left cell. Therefore, the eighth character is used to provide a left border for the upper cell.
[0045] In step S234, if neither the upper cell nor the target cell has a left border, they are merged, and the tenth character is used as the top left border character.
[0046] In another embodiment, after step S231 is performed, the following steps are included, but are not limited to: S2311, Determine the cell preceding the target cell, where the preceding cell is the row cell of the target cell in the column preceding the target row; S2312, when both the target cell and the preceding cell have top borders, maintain the ninth character as the top left border character; S2313, When the target cell has a top border and the preceding cell does not have a top border, change the top left border character to the fifth character; S2314, When the target cell has no top border and the preceding cell has a top border, change the top left border character to the sixth character, where the sixth character is used to represent the right side of the table that is not the top or bottom border; S2315, When the target cell has a left border and the preceding cell has no top border, change the top left border character to the eleventh character; S2316: When the target cell has no left border and the preceding cell has no top border, change the top left border character to empty.
[0047] It should be noted that in step S231, when it is determined that the top left boundary character is the ninth character, only the case of the two cells above and below is considered. However, in step S231, the target cell is not located in the first column, so it is also necessary to determine whether the top table line is hidden between the target cell and the cell in front of the previous column.
[0048] In step S2312, when both the target cell and the preceding cell have top borders, the ninth character is maintained as the top left border character; In step S2313, if the target cell has a top border and the preceding cell does not, then the table line of the preceding cell is hidden. The ninth character needs to be changed to the fifth character to avoid forming a top border in the preceding cell.
[0049] In step S2314, when the target cell has no top border and the preceding cell has a top border, the top table line of the target cell is hidden, and the top left border character is changed to the sixth character.
[0050] In step S2315, when the target cell has a left border and the preceding cell has no top border, the table line of the preceding cell is hidden, and the top left border character is modified to the eleventh character.
[0051] In step S2316, when the target cell has no left border and the preceding cell has no top border, both cells hide the table lines, and the top left border character is changed to empty, so that the top left border character is not printed.
[0052] In another embodiment, in step S12, the number of tenth characters is determined based on the top width, which specifically includes, but is not limited to, the following steps: S31, based on the target row that is not the first row, if the number of columns in the target row is less than the previous row in the target table, replace the tenth character at the end of each column in the previous row with the eighth character; or, if the number of columns in the target row is greater than the previous row in the target table, replace the top left boundary character with the seventh character.
[0053] S32, when the growth attribute of the target table is horizontal growth, for each row cell, when the content width of the cell content is less than or equal to the preset column width, the number of tenth characters is determined according to the preset column width, or when the content width is greater than the preset column width, the number of tenth characters is determined based on the content width. Here, the growth attribute is used to characterize the expansion display direction after the content width exceeds the preset column width. S33, when the target table's growth attribute is vertical growth, determine the number of tenth characters based on the preset column width.
[0054] It should be noted that, referring to Figure 1 As shown, when the target row is not the first row, it's necessary to determine the top character to match the bottom character at the boundary of the previous cell. If the number of columns in the target row is the same as the previous row, no operations are needed in the middle string; the current top string can be maintained. If the number of columns in the target row is less than the previous row, the tenth character at the end of each column in the previous row is replaced with the eighth character, thus forming a border in the previous row using the upper part of the eighth character. If the number of columns in the target row is greater than the previous row, the top left boundary character is replaced with the seventh character, thus forming a new column border in the target cell.
[0055] It should be noted that when calculating the column width, the number of tenth characters to fill is determined based on the top width. The principle is explained using the preset column width of m as an example and the content width of the cell content as n.
[0056] When the target table's growth attribute is horizontal (meaning the column width increases horizontally when cell content exceeds the default column width), if n ≤ m, the column width will not increase after filling with content. The default column width is usually determined by the number of characters; for example, if the column width is 10 characters, m can be used as the number of the tenth character to create a target cell with a standard width. If n > m, the default list cannot satisfy the content filling requirement. In this case, n is used to determine the number of the tenth character, ensuring the target cell can display its content horizontally, achieving adaptive adjustment of the cell width.
[0057] It should be noted that vertical growth refers to vertical growth (i.e., increasing the row height to add a row to be displayed). In this case, there is no need to consider the display of cell content from a horizontal perspective; the number of tenth cells can be determined based on the preset column width.
[0058] In another embodiment, in step S12, determining the top right boundary character specifically includes, but is not limited to, the following steps: S41, when the target cell is not located in the last column of the target row, set the top right margin character to empty; S42, when the target cell is located in the last column of the target row, and the target row is the first row of the target table or is in single-row mode, the third character is determined as the top right boundary character, where the third character is used to represent the top right corner of the table; S43, when the target cell is located in the last column of the target row, and the target row is not the first row of the target table or is in multi-row mode, when the target cell has a top border, the sixth character is determined as the top right border character, or when the target cell has no top border, the eleventh character is determined as the top right border character.
[0059] It should be noted that when determining the character to the right of the top boundary, first determine whether it is the right boundary through step S41. The right boundary is the last column of the target row. If the target cell is not the last column, the character to the right of the top boundary can be left blank.
[0060] When the target cell is in the last column, it's necessary to distinguish whether it's in single-row or first-row mode. In step S42, if the target cell is in the top right corner of the first row or single-row mode, the third character shown in Table 1 is used as the top right border character. In step S43, if the target cell is not in the first row or single-row mode and has a top border, the sixth character is determined as the top right border character, and the horizontal part of the sixth character is used as the top border. If there is no top border, the eleventh character is used.
[0061] In another embodiment, in step S13, the left-hand middle character, cell content, and right-hand middle character of each row cell are serialized into an intermediate string, which specifically includes, but is not limited to, the following steps: S51, when the middle left character and the middle right character are configured to be hidden, set the middle left character and the middle right character to empty; otherwise, set them to the eleventh character. S52, determine the number of characters to fill and the content text of the target cell, and divide the content text into multiple lines of sub-text; S53, when the target cell is in multi-line mode, construct the cell content based on the multi-line sequence content, wherein the sequence content includes fill string, subtext, fill string and newline character in sequence, the last line sequence content does not include newline character, the fill string includes multiple fill characters, and the number of fill characters in each fill string is half the number of fill characters; S54, when the target cell is in single-row mode, construct the cell content based on the fill string, the content text, and the fill string.
[0062] It should be noted that when serializing the intermediate string, the characters on the left and right sides need to be judged first, and then the cell content is assembled. In step S51, when the characters on the left and right sides of the middle string are configured to be hidden, they are each set to empty. Those not configured to be hidden are used with the eleventh character. For example, if the characters on the left side of the middle string are not hidden and the characters on the right side of the middle string are hidden, then the eleventh character is used, and the characters on the right side of the middle string are set to empty.
[0063] It should be noted that cell content can be displayed in multiple lines, depending on whether it is single-line or multi-line mode. The fill character can be a space. Therefore, the number of fill characters can represent the length. Taking the number of fill characters as t, the column width as m, and the width of the content text as r, then t=mr.
[0064] When the target cell is in multi-line mode, the cell content sequence is t / 2*L+first line sub-text+t / 2*L+'\n'+t / 2*L+second line sub-text+t / 2*L+…, where '\n' is a newline character.
[0065] When the target cell is in single-row mode, the cell content sequence is: t / 2*L + content text + t / 2*L.
[0066] In another embodiment, in step S14, when the target row is located in the last row of the target table, the bottom string is obtained by serializing the bottom left character, cell content, and bottom right character, specifically including but not limited to the following steps: S61, the second character is determined as the bottom left character of the first row cell, where the second character is used to represent the bottom left corner of the table; S62, based on any non-first row cell, if the bottom left character is configured to be hidden, determine the tenth character as the bottom left character; otherwise, determine the eighth character as the bottom left character. S63, the fourth character is determined as the bottom right character of the last row cell, and the bottom right characters of the remaining row cells are set to empty, where the fourth character is used to represent the bottom right corner of the table; S64 determines the bottom width of each row cell based on the number of fill characters.
[0067] It should be noted that the bottom string is only generated at the bottom of the table. When the target row is the last row, the characters on the left and right sides need to be determined. The first row cell in the first column is the bottom left corner of the table, and the bottom left character is the second character shown in Table 1. For rows that are not in the first column, if the bottom left character is set to hidden, the tenth character is used as the bottom right character to avoid the appearance of the left character; otherwise, the eighth character is used, and the character above the eighth character is used as the left character.
[0068] It should be noted that when determining the bottom right character, you only need to set the last row cell to the fourth character to form the right boundary, and leave the rest empty.
[0069] In another embodiment, in step S15, a preview table of the target table is generated based on the row printing information of all target tables, which specifically includes, but is not limited to, the following steps: S71, search for multiple optional fonts, where the optional fonts include multiple classes of available characters with different language types; S72, when the target font is found, the padding character is set to a space, and the width of the space between the padding characters of different types of available characters is determined according to the preset width ratio, wherein the multiple types of available characters of the target font are of equal width; S73, when the target font cannot be found, the padding character is determined to be a tab character, and the width of the tab character is set to a unit pixel width; S74 determines the number of fill characters based on the width of the row cell, the width of the cell content, and the width ratio.
[0070] It should be noted that when previewing the target table, different operating systems have different font libraries. In this embodiment, the system first determines whether to use spaces or tabs as fill characters based on the character font width.
[0071] In this embodiment, when searching for the target font, it is necessary to ensure that the widths of different types of characters are equal. This is because the width of the strings mentioned above in this embodiment is adjusted based on the content, and the number of the top tenth characters is determined by the character width. If the widths of different types of characters are not equal, it can easily affect the display. Therefore, this embodiment uses characters with equal width as the target font, such as Chinese characters, English characters, and special characters (such as Ω) with equal width. If the search finds a font with the default fill character set to a space, the width ratio of single characters to wide characters needs to be configured. For example, for platforms such as Windows, the default width ratio is 1:2, that is, the width of Chinese characters and special characters is twice the width of a space and the width of English characters; for other platforms, the width ratio is 1:p, and the number of fill characters is (cell width – content width) * p, where p is a positive number.
[0072] It should be noted that if no fixed-width font size is found, the padding character will be set to a tab character, and the tab character width will be set to 1 pixel. For other platforms where fixed-width characters cannot be found, let the pixel width of the content text be w, then the number of padding characters will be (cell width – content width) * w.
