Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a desktop publishing system (hereinafter referred to as DT) that can freely create and edit tables in a document.
P)) and a table editing method.

[Related Art] In recent years, a table editing apparatus such as a DTP capable of freely creating a table in a document and performing various editing on the table has been required to have various functions and to improve operability. .

In a conventional table editing apparatus, when a table is created in a document, a method for sequentially drawing a rectangle, a vertical line, and a horizontal line, a so-called drawing function, and a method for sequentially designating the size, the number of rows, and the number of columns of a table, a so-called table There is a function. In the former case, a rectangle created by drawing a line is recognized as one cell, and the table is managed independently for each cell in the table. In the latter case, the table is managed in units of rows and columns.

[Problems to be Solved by the Invention] However, in a conventional table editing apparatus, when a table is created by drawing a line, a row or column is inserted into the table or a row or column in the table is deleted. Has no concept of a matrix, so the parts of the table that change due to insertion or deletion must be corrected by moving or redrawing lines. In addition, when a table is created by specifying a matrix, editing can be performed only in units of rows and columns, and it is difficult to insert hatched lines.

In other words, there is no relation between the table created by the table creation function and the figure created using the drawing function. Even if the size of the table is changed or the position of the line is moved, it is inserted using the drawing function. Since the position and length of the oblique lines do not change, it was necessary to change the figure created using the drawing function each time the table was changed.

[Means for Solving the Problems] In order to solve this problem, the present invention is based on storage means for storing table data composed of a plurality of row data, column data, and the like, and table data stored in the storage means. Ruled line generating means for generating ruled line data constituting the table; drawing means for generating line segment data in the table data based on start and end points; and table changing means for changing the ruled line data generated by the ruled line generating means With the change of the ruled line data by the table changing means, the coordinate data is set to the end point position of the line segment data created by the drawing means which coincides with the intersection point of the ruled line data, and the coordinate data of the changed intersection point position is changed. And changing means for changing the coordinate data so as to coincide with the above.

[Operation] According to the configuration, when there is line segment data drawn by the drawing function in a table created by the table drawing function, a line that coincides with the intersection position of the ruled line data with the change of the ruled line data. Since the coordinate data is changed so that the coordinate data of the end point position of the minute data matches the coordinate data of the intersection point position after the change, in the cell where the end position of the line segment data and the intersection position of the ruled line data match, The diagonal is always maintained.
