DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tabulation support apparatus, and more particularly to a tabulation support apparatus that supports creation of a table using an electronic computer.

[0002]

2. Description of the Related Art In a conventional table support device, the position of a ruled line is fixed during character input, or a line feed is selected at the last line of a frame surrounded by the ruled line, or until the last line is full. When a character is input, it has a function to move the ruled line of the last line by one line and enlarge the frame.

[0003]

In the above-described conventional table creation support device, when the ruled line position during character input is fixed, characters are likely to overflow from the frame surrounded by the ruled line during table creation. In this case, it is necessary for the user to explicitly stop character input and expand the frame, that is, move the ruled line, and to interrupt the flow of character input operation. -There is a problem that the burden on the user is large psychologically.

In the method of moving the ruled line of the last line by inputting a new line in the last line, there is no problem if the table is to be expanded in the row direction. It is necessary to interrupt the input and move the ruled line explicitly, which again has a problem that the burden on the user is large.

SUMMARY OF THE INVENTION An object of the present invention is to provide a table support apparatus having a function of performing an operation of enlarging a table in a row direction and an operation of enlarging a table in a column direction by a character input operation in order to solve the above-mentioned problems of the prior art. Is to do.

[0006]

According to the present invention, there is provided a tabulation support apparatus comprising: input means for inputting a character and a ruled line; character holding means for holding a character to be displayed; and ruled line holding means for holding a ruled line to be displayed. A ruled line input determining means for comparing the output from the input means with the contents of the ruled line holding means to determine whether or not the character input has been performed on the ruled line; While storing in the character holding means so as to be displayed at the position where the input has been performed, when the on-ruled line input determination means determines that the character input has been performed on the ruled line, the corresponding ruled line is moved,
A display changing means for changing the contents of the contents and the character holding means of the ruled line retaining means to move the string as necessary to not move ruled line and weight, the content of the character holding means and the Display means for displaying the contents of the ruled line holding means. The table creation support device of the present invention includes an input unit for inputting a character and a ruled line, a character holding unit for holding a character to be displayed, a ruled line holding unit for holding a ruled line to be displayed, and an output from the input unit. A ruled line input determining means for comparing the contents of the ruled line holding means with the contents of the ruled line to determine whether or not the character input is performed on the ruled line; and displaying the character input from the input means at the position where the character input is performed. When the input determination means on the ruled line determines that the character input has been performed on the ruled line, the corresponding ruled line is moved so that it does not overlap with the moved ruled line. Display contents changing means for changing the contents of the ruled line holding means and the contents of the character holding means so as to move the character string in accordance with the following, and the contents of the character holding means and the contents of the ruled line holding means A display direction holding unit that holds selection information input from the input unit as to whether to display a character string in a vertical writing mode or a horizontal writing mode. The contents changing means uses the contents of the selection information held by the display direction holding means when changing the contents of the ruled line holding means or the contents of the character holding means, and each of the ruled lines held in advance by the ruled line holding means. A moving attribute for designating whether the object is movable or fixed is provided from the input means in advance, and the movement attribute holding means holds the movement attribute. The display content changing means includes the contents of the ruled line holding means or the character holding means. When changing the content of the moving attribute, the moving attribute held in the moving attribute holding means is used.

[0007]

According to the tabulation assisting apparatus of the present invention, the characters input to the input means are sent to the ruled line input determining means and the display content changing means.

The ruled line input determining means refers to the contents of the ruled line holding means, determines whether or not a character input has been performed on the ruled line, and outputs the result.

The display content changing means changes the contents of the character holding means so that the input character is displayed at the position where the input was made when the input determination means on the ruled line determines that the input is not on the ruled line. . In this case, the contents of the ruled line holding means are not changed.

On the other hand, when the ruled line input determining means determines that the input has been made on the ruled line, the ruled line input determining means changes the contents of the character holding means so that the input character is displayed at the position where the input was made, and The contents of the holding unit are changed, and the ruled line existing at the position where the character is input is moved. At this time, if it is necessary to move the character string in order to maintain display consistency, the movement is performed simultaneously.

Finally, the output means displays the contents of the character holding means and the contents of the ruled line holding means.

Further, in the tabulation support apparatus of the present invention, the distinction between the vertical writing display and the horizontal writing display is held in the display direction holding means, and the display content changing means selects the ruled line moving direction using the contents. I do. For example, when a character is input on a vertical ruled line, the horizontal ruled line is moved to the right by one line if horizontal writing is performed, and the vertical ruled line is moved to the left by one line if vertical writing is performed To do it. As a result, it is possible to perform appropriate ruled line movement according to whether vertical writing or horizontal writing is to be performed.

Further, the table creation support apparatus of the present invention is used when a ruled line is moved by assigning a movement attribute to the ruled line. For example,
During character input, ruled lines having a movable attribute are allowed to be automatically moved, but ruled lines having a fixed attribute are not automatically moved. As a result, it is possible to avoid the movement of the ruled line to be fixed during the character input.

[0014]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the present invention.

Referring to FIG. 1, the first embodiment is characterized in that an input unit 1 and a display unit 6 for inputting characters, ruled lines and the like and displaying them, a character string on a screen and a character string storing its display position. By comparing the input character with the display position of the current ruled line, the ruled line holding unit 3 storing the ruled line on the screen and its display position is compared with the ruled line currently displayed. A ruled line input determination unit 5 for determining whether or not an input has been made on the screen, and outputting a determination result;
And is configured.

The display content change unit 2 includes a ruled line input determination unit 5
If it is determined that the input is not on the ruled line, the character holding unit 3 displays the input character at the position where the input was made.
Change the content of For example, the character code of the input character is stored in a storage area in the character holding unit 3 corresponding to the position on the screen where the input has been performed. In this case, the contents of the ruled line holding unit 4 are not changed.

On the other hand, when the ruled line input determining unit 5 determines that the input has been made on the ruled line, the ruled line is moved by one line or one column, and necessary changes are made to the character holding unit 3 and the ruled line holding unit 4.

FIGS. 2A and 2B are diagrams showing an example of ruled line movement in the first embodiment. FIG. 2A is a diagram showing a display example of ruled line movement input, and FIG. 2B is a diagram showing a case where the ruled line is moved. is there.

Next, the operation of the first embodiment when an input is made on a ruled line will be described with reference to FIGS.

FIG. 2A shows an area 10 surrounded by ruled lines.
This is a display example in which the input of characters into the area 10 has been continued and the input to the position of the lower right corner 20 of the area 10 has been completed. The cursor indicating the next input position is located at a position 30 above the ruled line at the lower left of the area 10. When a character is input in this state, the ruled line input determination unit 5 determines that the input has been performed on the ruled line 40 and notifies the display content change unit 2. The display content changing unit 2 enlarges the area 10 by, for example, shifting the display position of the ruled line 40 down by one line and performing an operation of appropriately extending a necessary vertical ruled line. The input characters are inserted at the beginning of the resulting blank line. FIG. 2B shows a display immediately after the character “A” is input in the state of FIG. 2A.

At this time, if a character exists immediately below the ruled line 40, it is necessary to simultaneously move the character so as not to overlap the moved ruled line. Add.

FIG. 3 is a block diagram showing a second embodiment of the present invention.

In FIG. 3, the second embodiment has a display direction holding unit 7 in addition to the configuration of the first embodiment shown in FIG. When changing the display position, the content to be changed is determined using the content.

For example, if an input is made on a vertical ruled line in the horizontal writing display, the ruled line is moved one line to the right to enlarge the frame. In the vertical writing display, the ruled line is shifted to the left. Select to enlarge the frame by moving.

FIG. 4 is a flow chart showing the operation of the display content changing section in the second embodiment.

Next, the operation of the display content changing section 2 in the second embodiment will be described with reference to FIGS.

The operation performed by the ruled line input determining unit 5 when it is determined that the input is not on the ruled line is the same as the operation of the display content changing unit 2 in the first embodiment.

The operation when the ruled line input unit 5 determines that an input has been made on a ruled line will be described with reference to FIGS.

The display content changing unit 2 includes a ruled line input determination unit 5
Then, it is determined whether or not the ruled line input thereon is a horizontal ruled line based on the information from (S11).

If it is a horizontal ruled line, the ruled line is moved down by one line (S13).

On the other hand, if the ruled line input on the line is not a horizontal ruled line, the display content changing unit 2 refers to the contents of the display direction holding unit 7 to determine whether the current display is horizontal writing display or not. Is determined (S12).

If the display is horizontal, the corresponding ruled line is moved rightward (S15).

If the display is not horizontal writing, the corresponding ruled line is moved to the left (S14).

After the movement of the ruled lines, finally, the character holding unit 3 and the ruled line holding unit 4 are operated so that no inconsistency occurs in the display.
Then, necessary changes are made to the stored contents (S16), and the display contents change is terminated.

FIG. 5 is a diagram showing an example of the contents held in the ruled line holding unit in the first embodiment and the second embodiment of the present invention.

In FIG. 5, each ruled line has a starting point position 101
, Position attribute of end point position 102, line type 103 and thickness 10
In addition to the line attribute and the protection attribute 105 of FIG. Display content changing unit 2 based on the character overflow detection signal from ruled line input determination unit 5
Does not change the position of the ruled line having the fixed attribute shown in FIG. 5 when calculating the moving position of the ruled line.

In the example shown in FIG. 5, only a horizontal ruled line below a frame surrounded by four ruled lines is movable, and the ruled line moves downward only when a character is input on the ruled line. Will be.

[0039]

As described above, according to the present invention, even if it is necessary to move a ruled line to create a frame while creating a table, character input operation can be performed without interrupting character input. There is an effect that can be performed. This operation can be performed on any ruled line, regardless of whether the table is expanded in the row direction or the column direction.

The present invention also provides a method for automatically moving a ruled line by moving the vertical ruled line to the left in the case of vertical writing and moving the vertical ruled line to the right in the case of horizontal writing. There is an effect that the moving direction of the image can be appropriately selected.

Further, according to the present invention, some of the ruled lines whose positions are desired to be fixed during character input are present. By distinguishing a movable ruled line which may be moved by a user from a fixed ruled line which is prohibited from moving except for explicit movement, the display content changing means uses this information when calculating the moving position of the ruled line. There is an effect that the automatic movement of the fixed ruled line can be prohibited.
