Problems solved by technology

[0005] I believe that complex formulas similar to formula 1 are not easy to understand for users who are not the author of the formula itself, even if the author of the formula itself reads this formula again after a period of time, it will not be easy to understand
[0006] However, in practical applications, a spreadsheet is often transferred from one user to another user, or a fixed user checks the spreadsheet from time to time
If the spreadsheet contains complex formulas, it is inconvenient for users to understand the formulas
In addition, some other formulas or expressions such as teaching applications or engineering calculation applications also have such problems, resulting in poor user experience of these applications

Abstract

The invention discloses a dendriform display method of an expression, wherein, the expression contains a plurality of operational symbols and original data types. The method comprises the following steps: the operational symbol with the lowest priority in the expression is displayed as a root node; a processing object of the operational symbol is displayed as a child node or a subtree; if the processing object of the operational symbol is the original data type, the processing object is displayed as a child node; if the processing object of the operational symbol is a subexpression, the processing object is displayed as a child node in case of no expansion and is displayed as a subtree in case of expansion, that is, the operational symbol with the lowest priority in the expression is displayed as a root node of the subtree; and the processing object of the operational symbol with the lowest priority in the expression is continuously displayed as a child node or the subtree. In the invention, hierarchical dendriform display is realized according to the operation priority of the expression or a formula and the relation between the operational symbols and data so that a user can more easily understand the meaning of the expression.

Description

【Technical field】 [0001] The invention relates to the field of user interface display, in particular to the tree display of expressions and its application in electronic forms. 【Background technique】 [0002] Various applications accept, manipulate, and display content on graphical user interfaces such as Microsoft Corporation's Windows operating system, Google Corporation's Android operating system, and Apple Inc.'s MacOS operating system. For example, the spreadsheet program in the OFFICE application program of Wuxi Yongzhong Technology is an application program that displays data in various formats on a graphical user interface. Spreadsheet applications, or apps, are relatively well-known and useful tools. Spreadsheet applications typically emulate formal data tables by capturing, displaying, and manipulating data arranged in rows and columns. Intersecting rows and columns form many cells in a spreadsheet. Typically, each cell will contain a data item and / or a mathemat...
