Abstract

PURPOSE: To obtain a visually balanced centering display and to make the layout of the whole of a table easy to be seen by performing the blocking based on the grouping of table cell data before the centering of table cell data. CONSTITUTION: As shown in (a), a case where table data composed of 7-byte data is inputted in each table cell in a 5-line and 1-column table is supposed. In this case, the number of column is investigated at first and table cell data is grouped for every column. In this case, the number of group becomes 1. Next, the maximum value of the number of byte of the area where data exists in each table cell within each group is determined. In this case, the value is 3 bytes. Next, the data of each table cell is blocked by the length of MAX=3 bytes, the data is written in a cell block buffer, and processings of a justification to the right, a justification to the left and a centering are performed for each block data for every type of data. In this case, the processing is the justification to the right. Next, the data within justified to the right buffer is written and displayed within the block of each table cell for which the centering is performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table processing device, and more particularly to a centering process of a layout process of table data in spreadsheet software and text creation software used in computers and word processors.

[0002]

2. Description of the Related Art In conventional table data centering processing, the size of data is judged in each table cell,
The data was centered and displayed. FIG. 4 is a diagram showing an example of such a conventional centering display method.

In FIG. 4, when data is displayed as shown in FIG. 4A before centering, the size of the data in each table cell is judged and
As shown in (b), centering is displayed.

[0004]

However, when the centering is performed based on the size of each data to be displayed, the display becomes difficult to see due to the correlation between the characteristics of each data itself and the data above and below the table. There was a problem of being lost. An object of the present invention is to provide a layout display that makes the layout of the entire table easier to see.

[0005]

The means of the present invention are as follows. The grouping means groups each table data arranged in a plurality of table cells arranged vertically and horizontally according to a predetermined rule. The blocking means calculates the data effective area in each table cell for each same group of the grouped table data, and blocks the data in each table cell based on the calculation result. The layout processing means performs a layout process on the block table data in block units.

[0006]

The operation of the means of the present invention is as follows. First,
The table data arranged in a plurality of table cells arranged in each of the vertical and horizontal directions are grouped according to a predetermined rule by the grouping means, for example, column by column. Next, the data effective area in each table cell, for example, the maximum number of bytes in which the data exists is calculated for each same group of the grouped table data, and each table is calculated by the blocking means based on the calculation result. Block the data in the cell. Then, the block-structured table data is laid out in block units by the layout processing means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. FIG. 1 is a block diagram showing the configuration of a table processing device to which the present invention is applied. In the figure,
Reference numeral 2 is a CPU, which controls each part described below. An input device 1 is composed of a keyboard, a mouse and the like having input function keys. An operation signal generated when a user operates the input function key of the input device 1 is transferred to the CPU 2 and a predetermined process is executed. A data memory 3 stores table data created by the user. A program RAM 4 stores a program for performing processing such as input control and table editing. Reference numeral 5 is a display memory for storing display data in a dot pattern, and the table data stored in the data memory 3 is stored in C
A display image obtained by conversion under the control of PU2 is stored. The data in the display memory 5 is displayed on the display unit 7 via the driver 6.

The operation of the above configuration will be described below with reference to FIG. In this example, in the data in each table cell,
It focuses on the fact that there is a correlation between the characteristics of the data in the table cells above and below or to the left and right. Then, the maximum number of bytes) is calculated, and the centering process is performed for each block having a fixed data length.

In such a centering process, the operation flow of the centering process of the right-justified data type, that is, the data arranged right-justified in the table will be described below. Here, as shown in FIG. 2A, it is assumed that table data in which each table cell is 7 bytes of data is input in the table of 5 rows and 1 column. A. First, when such table data is input, the number of columns is checked, and table cell data is grouped for each column.
Since the number of columns is 1 here, the number of groups is also 1. B. Next, the maximum value (MAX value) of the number of bytes in the area where data is present in each table cell in each group is obtained. Here, MAX = 3 bytes. C. Next, the data of each table cell is divided into blocks with a length of MAX = 3 bytes, and written into the cell block buffer. Then, for each block data written in the cell block buffer, right-justified, left-justified, and centering processes are performed for each data type (feature). Right-justified processing is performed here (FIG. 2B). D. Next, the data in the right-justified buffer is written and displayed in the centered block of each table cell (FIG. 2C).

Next, the above operation will be further described with reference to the processing flowchart of FIG. In the figure, S0 to S9 indicate operating states. First, the process is started from the state S0. In the state S1, the processing of the operation flow A described above is performed. Next, the process of operation flow B is performed in state S2, and the process of operation flow C is performed in states S3 and S4. Further, in states S5 and S6, the process of operation flow D is performed.

In this way, the processing of state S7 is performed for the number of data in the same group, the processing of state S8 is performed for the number of groups at the time of grouping, and the processing of state S9 ends.

According to the present embodiment described above, instead of centering the table cell data according to the size of the data as in the prior art, the fixed length of the data in the group, for example Since the centering display is performed in block units of the maximum number of bytes in the existing area, it is displayed in a state shifted from the center in the table cell depending on the type of data, and the layout of the entire table becomes easier to see.

Although the centering process of the right-justified data type has been described in the above embodiment, the present invention is not limited to this and can be applied to the centering process of the left-justified data type. The present invention can be applied not only to the centering process but also to other layout processes.

[0014]

According to the present invention, since the table cell data is centered before being centered, the blocks are formed based on the grouping of the table cell data. A visually well-balanced centering display can be realized, and the layout of the entire table becomes easier to see.
