When querying the information of the column with the merge operation, the returned result is still the information of the column before the change, which visually disturbs the user
In particular, there are many merge operations of rows or columns in the table, and there are correspondingly many cells with position changes. The content of the column seen during the query and the content of the column of the query result actually returned will be very different. The content in the table structure has changed too much, and it is not visually beautiful
Furthermore, when performing a merge operation, the display content of the occupied cell is deleted. On the surface, only the content of individual columns is changed, and the content of the original table is not changed much. However, when querying the content of this column, other The display still includes the contents of the cells that have been shifted back, and the interference still exists, which is not conducive to the maintenance of the table

Embodiment Construction
[0015] In order to make the method for realizing HTML table column operation mentioned in the present invention and its advantages clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0016] figure 1 It is a flowchart of an embodiment of a method for implementing HTML table column operations provided by the present invention. Such as figure 1 As shown, the main flow of the method is as follows:
[0017] Step 1, add custom column attributes in the table TD node.
[0018] When the table is initialized, the sequence value of the column where each TD node is located is saved in this custom attribute.
[0019] Step 2, add a merge operation.
[0020] There are two ways of merging here: merging across rows and merging across columns. Each merging operation is divided into two cases of increasing and decreasing merging, and corresponding merging operations are performed according to actual needs during operation. ...

The invention provides a method for realizing HTML (HyperText Markup Language) table column operation. The method comprises the following steps: adding customized column properties into TD nodes; during initialization of a table, saving the sequence values of columns where each TD node is positioned in the customized properties; forming TD nodes of corresponding columns through matched columns of the customized properties. By adopting the method, corresponding column values displayed are accordant with result values returned by practical inquiry after rowspan or colspan operation on an HTML design table. Meanwhile, the defects on the aspect of table design of an HMTL language are overcome, and good user experience is provided in a more effective way.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a method for realizing column operations in HTML tables. Background technique [0002] HTML is the key to the world of Web technology, and is widely used for its simplicity, scalability, and platform independence. Whether in everyday life and work, or in web design, tables often make information easier to understand. HTML has a strong table function, so that users can easily create tables of various specifications, and can make specific adjustments and modifications to the table, so that the web page can better meet the needs. When merging tables in HTML, the attributes used include merging across rows: rowspan and merging across columns: colspan. By setting the value of the attribute, the merging of rows or columns can be realized. [0003] However, after the merging operation of HTML, there are certain problems in the display of the web page, which has a considerable impact...
