Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruled line position determining device for a table when a document and a table are created by a document processing device in a word processor, a personal computer, a workstation or the like. The word processor, personal computer,
Alternatively, a device that creates and processes documents and tables by a workstation, etc.
It is simply described as "document processing device".

[0002]

2. Description of the Related Art FIGS. 11 (a) to 11 (d) are views for explaining a case of drawing a ruled line in a conventional document processing apparatus. A document processing apparatus that creates a document together with a table handles ruled lines as codes in the same manner as characters. As described above, in the document processing apparatus in which both ruled lines and characters are handled in the code system, an editing program for editing tables and documents can be simply and easily created. However, in the above document processing apparatus, for example, a character "aiueo" is added to a rectangular area of the table shown in FIG. 11A (hereinafter, "rectangular area of table" is simply referred to as "cell" in this specification). Was inserted. When a horizontal ruled line is drawn in the center of this table, "u" and "e" disappear and
It becomes like (b). That is, since both characters and ruled lines are codes, “u” and “e” are overwritten by the horizontal ruled lines.

Further, in the case of increasing or decreasing the contents in cells in a matrix table, a line feed mark is put in the table shown in FIG. 11C, for example. However, Fig. 11 (d)
As shown in, the vertical ruled line is
Since there is a non-continuous part, it was necessary to put vertical ruled lines in that part for repair. Therefore, in the matrix-shaped table, the operation becomes complicated to increase or decrease the content in the cell.

In the above matrix-like table, there is a technique designed to prevent characters from being erased when a horizontal ruled line is drawn. For example, in the table frame shaping method described in Japanese Patent Laid-Open No. 3-38774, when the size of the designated cell is changed, the size of the designated cell is changed to the other cells in the same row and column. The size of each row and column is provisionally determined according to the arrangement of the text data. Next, according to the overflow of the text data of each cell, the size of the row and column contained in that cell is corrected.

Further, as a device capable of automatically repairing a frame in a matrix-shaped table, for example, Japanese Patent Laid-Open No. 3-77.
There is a data processing device described in Japanese Patent Publication No. 127. When adding or deleting data in the cells that make up the table and changing the data length, this data processing device automatically displays the display frame that displays the cell that contains the data according to the change in the data length. Can be changed.

Further, there is a method in which ruled line data and character data are separately structured and managed, and these are combined and considered as table data. For example, Japanese Patent Application No. 2-320701 (November 2, 1990) previously proposed by the present applicant.
The table creation processing device in (7th application) separately stores ruled line data indicating ruled lines and cell data indicating cell contents, and also sets vertical and horizontal ruled line data and attribute data of cells formed by the ruled lines. By matching with and, the ruled line can be moved, added, regardless of the characters in the cell,
Or you can delete it. This allows you to freely edit tables (moving rules, adding rules,
Can be deleted).

[0007]

The table preparation device proposed by the applicant of the present invention stores character data and ruled line data forming a table, and gives an instruction from the operator to move, add, or delete ruled lines. In response, the cells are divided and combined, so that a non-matrix table can be created.

However, the non-matrix table does not take into consideration the process of automatically changing the interval between the horizontal ruled lines when performing editing work such as changing the size of characters or increasing the number of characters. It was

The present invention is intended to solve the above problems, and performs editing work such as changing the size of characters or increasing the number of characters in a cell of a table that allows non-matrix. Even so, an object of the present invention is to provide a table ruled line position determining device capable of automatically changing the interval between the horizontal ruled lines.

[0010]

A ruled line position determining device for determining a ruled line position of a table that allows a non-matrix shape is a ruled line information storage unit (131 in FIG. 1) that stores information indicating the position of the ruled line. ), A rectangular area information storage unit (132 in FIG. 1) for storing information consisting of the attributes of the rectangular area and the contents described in the rectangular area, and all two horizontal lines in the rectangular area forming the table. First ruled line interval determination processing means for searching a rectangular area formed by two horizontal ruled lines and determining the widest interval in each of the rectangular areas when the ruled line interval and the table are edited (Fig. 1
No. 111), second ruled line interval determination processing means (112 in FIG. 1) for determining the interval between two consecutive horizontal ruled lines, the first ruled line interval determination processing means (111) and second ruled line interval determination processing. Based on the spacing determined by the means (112), it comprises a ruled line spacing alignment processing means (113 in FIG. 1) for automatically rearranging the edited horizontal ruled lines sequentially from the uppermost reference line.

[0011]

[Operation] The table ruled line position determining device in the present invention is
When editing the contents of the rectangular area of the table that allows non-matrix shapes composed of rectangular areas and ruled lines,
The feature is that the horizontal ruled line interval is automatically expanded or reduced to fit the horizontal ruled line to the contents in the rectangular area.

The ruled line information storage means stores the position of the ruled line, for example, the start and end points of a horizontal or vertical ruled line, and the shape of the ruled line, such as a solid line, a thin line, and a dotted line. The rectangular area information storage means stores data representing the contents described in the rectangular area surrounded by the ruled line information stored in the ruled line information storage means. Then, the first ruled line interval determination processing means calculates the interval for every horizontal ruled line in the table, and determines the interval between the respective horizontal ruled lines. Further, the first ruled line interval determination processing means, when a new table is edited, for example, when an editing operation such as changing the size of characters in the rectangular area or increasing the number of characters is performed, two horizontal lines are arranged. The rectangular areas formed by the ruled lines are searched, and the widest interval in those rectangular areas is determined. Further, the second ruled line interval determination processing means determines the interval between two continuous horizontal ruled lines based on the interval between all the two horizontal ruled lines determined by the first ruled line interval determination processing means. Do the calculations for.

After that, the ruled line interval alignment processing means determines the positions of all the horizontal ruled lines based on the interval between the two continuous horizontal ruled lines, and automatically edits the edited horizontal ruled lines sequentially from the uppermost reference line. Relocate to. Therefore, when a new table is edited, for example, when the size of the characters written in each rectangular area changes or the number of characters increases, the interval between the horizontal ruled lines is automatically expanded or reduced. That is, a character or the like in the edited rectangular area does not have a useless blank for being displayed or displayed outside the rectangular area.

FIG. 4 is a flow chart showing an example of creating a table using the table ruled line position determining device according to the present invention.
4, when creating the table, one point on the table is selected by the mouse 18 or the keyboard 19 in FIG. Then, the ruled line or cell indicated by the selected point is determined. In this way, the fixed target is instructed by the user and the editing operation is performed. That is, the document including the table is edited (step 41).

Next, when a document having characters in cells is edited, horizontal ruled lines are determined so that the characters fit the size of the cells of the table, and the horizontal ruled line data of the table is corrected. In the present specification, "editing" includes not only editing by characters but also editing by changing ruled lines. For example, when a character is input in a cell to edit a table, the character may be too large or a character with a high height may be used, so that the character may extend beyond the horizontal ruled line and cannot be seen. In addition, there are cases in which a large space is created above or below a horizontal ruled line or on one side of the horizontal ruled line because the number of characters is reduced or characters with a low height are used. In such a case, the table is automatically expanded / contracted by the means described later (step 42). The automatic scaling will be described in detail next with reference to FIG. The table edited by the automatic scaling is displayed on the display 16 under the control of the display control circuit 17 (step 43).

FIG. 8 is a diagram for explaining an example showing the cell size after the automatic scaling processing according to the present invention. FIG. 9 shows two consecutive lines in the present invention.
It is explanatory drawing for determining the horizontal ruled line of a book. In FIG. 6, the first ruled line interval determining means determines the interval W between all the horizontal ruled lines.
Determine i, j. That is, L0 and L1, L0 and L2,
L0 and L3, ..., L0 and Ln, L1 and L2, L1 and L3, L1 and L4, ... L1 and Ln, L2 and L3 ,.
..Ln, L3 and L4, ... Ln, ..., L (n-
The intervals Wi, j are determined for all combinations of two ruled lines, such as 1) and Ln.

Next, all cells divided by the horizontal ruled line Li and the horizontal ruled line Lj are searched. For example, the L0
, L1, L0 and L2, L0 and L3, ..., L0 and L
It is searched for each cell between the ruled lines for n, ..., Ln−1 and Ln one by one. That is, FIG.
Cell C1 between the horizontal ruled line H0 and the horizontal ruled line H3 as shown in FIG.
Since there is a case where there is a case, a cell is searched for a combination of all two horizontal ruled lines as described above. For example, assume that cells C11, C12, and C13 are searched between the horizontal ruled line Li and the horizontal ruled line Lj as shown in FIG. Then, the width after editing in each cell C11, C12, C13 is obtained. For example, from the upper and lower horizontal ruled line data of each cell, an interval corresponding to the width thereof is obtained, and the intervals are compared, and the one with the largest interval is selected.

The size of each cell after the above editing is checked. For example, as shown in FIG. 8, it is assumed that cell C11 has its width increased, cell C12 has its width reduced, and cell C13 has its width unchanged. The distance Wi, j between the edited horizontal ruled line Li and the horizontal ruled line Lj is determined by the cells C11, C12,
Determined to be the widest of C13. When a cell delimited by the horizontal ruled line Li and the horizontal ruled line Lj cannot be searched, for example, when the cell is deleted in the editing, the interval Wi, j between the horizontal ruled line Li and the horizontal ruled line Lj is set to be smaller than the width of the ruled line. It is a positive constant. By doing so, it is possible to prevent two consecutive horizontal ruled lines before editing from being reversed or overlapped. The above processing is performed in step 51 shown in FIG.

Next, the determination of the distance di between two continuous horizontal ruled lines will be described (step 52). Step 51
By using the interval Wi, j between the horizontal ruled lines obtained by the above, the interval di between two continuous horizontal ruled lines is sequentially determined. For example, in FIG. 3, the horizontal ruled line H3 cannot be determined only by W0,3 determined by the size of the cell C1.
That is, W0,3 (size of C1 of cell) and W0,1 +
It is necessary to select the widest one of W1,2 + W2,3 (size of cells C2, C4, C6 added) and W0,1 + W1,3 (size of cells C3 and C5 added) There is. Therefore, the following calculation is performed. Let d1 be the distance between the horizontal ruled line L0 and the horizontal ruled line L1. Since the widest cell among the cells between the horizontal ruled line L0 and the horizontal ruled line L1 is determined to be W0,1, this value is automatically determined to be d1 = W0,1.

The interval d2 shown in FIG. 9 is determined by the horizontal ruled line L0.
And L1, between horizontal ruled lines L1 and L2, and between horizontal ruled lines L0 and L
Since there is a possibility of having a cell between two, it is necessary to compare these intervals and make the largest interval. However, the distance d1 between the horizontal ruled lines L0 and L1 that has already been calculated
= W0,1 has been determined, so the widest spacing W1,2 between cells between horizontal ruled lines L1 and L2 and the widest spacing between cells between horizontal ruled lines L0 and horizontal ruled line L2 Interval (W0,2-d1) obtained by subtracting the previously determined interval d1 from W0,2
And a large interval is determined as d2. That is,
As shown in FIG. 10A, d2 ₁ = (spacing between horizontal ruled line L1 and horizontal ruled line L2) = W1,2
And d2 ₂ = (spacing between horizontal ruled line L0 and horizontal ruled line L2) = W0,2
-D1. d2 is the larger value by comparing the above d2 ₁ and d2 ₂ . d2 = max {W1,2, (W0,2-d1)} where d2 ≧ small positive constant.

Similarly, as shown in FIG. 10B, d3 ₁ = (spacing between horizontal ruled line L2 and horizontal ruled line L3) = W2,3
And d3 ₂ = (spacing between horizontal ruled line L1 and horizontal ruled line L3) = W1,3
-D1. d3 ₃ = (spacing between horizontal ruled line L0 and horizontal ruled line L3) = W0,3
-D1-d2. d3 is the larger value by comparing the above d3 ₁ , d3 ₂ and d3 ₃ . Similarly to the above, d3 = max {W1,2, (W1,3-d2), (W0,3-d1-d2)} Hereinafter, at d4, the comparison as shown in FIG. Here, d3 ≧ small positive constant.

A ruled line similar to the above is continued for the horizontal ruled line up to di. di ₁ = W (i-1), i, di ₂ = {W (i-2), i} -d (i-1), di ₃ = {W (i-3), i}-{d ( i-2) + d (i -1)}, ···· ···· di i = W0, it - {d1 + d2 + ··· + d (i-1)} di is _{di 1, di 2, di 3} , di ₄ , ... di _i
Is compared and set to the largest value. Here, di ≧ small positive constant. Here, di obtained as described above is Wi, j ≤ {d1 + d2 + d3 + ... + d (i-1)}
To be satisfied.

By the above calculation, the position of the interval di between two consecutive horizontal ruled lines is determined, and therefore, the highest horizontal ruled line L in the table is based on the interval di between the two consecutive horizontal ruled lines.
The positions of all the horizontal ruled lines Li are determined based on 0 (step 53). Here, since di ≧ a small positive constant, the positions of two consecutive horizontal ruled lines before editing are not reversed or overlapped with one after editing. For example, the position of the horizontal ruled line Li is determined by (d1 + d2 + d3 + ... + di).
Next, using the newly determined horizontal ruled line Li as table data, R
Writing to the ruled line information storage means 131 and the rectangular area information storage means 132 in the AM 13. After that, the above editing is repeated.
