Abstract
Abstract A table structure for table calculation software is employed to prepare an aggregate table and a numeric table by displaying ruled lines. A table structure is provided with which the degree of freedom for the designing of a table can be increased and table calculations can be easily performed. A data table structure, for a table having an irregular shape wherein a plurality of cells having different sizes are formed. Cell data areas store input data in the plurality of cells. Coordinate data areas, in addition to the cell data areas, store coordinate data for defining locations and sizes of input areas of the plurality of cells in the table.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
149 words
A table calculation method, in which result data is mathematically calculated for a plurality of cells which are arranged either in a direction of rows or in a direction of columns, comprising the steps of: defining a location and size for each of said plurality of cells by using elements of a matrix structure which is formed by extending all horizontal and vertical ruled lines that define said plurality of cells, wherein elements of the matrix structure have associated calculation data and wherein the location and size for at least one cell of the plurality of cells is defined by a plurality of elements of the matrix structure; and calculating the result data from the plurality of cells, wherein mathematical calculations including the at least one cell utilize calculation data associated with only one of the plurality of elements of the matrix which define the at least one cell.
Claim 2
Dependent Claim
149 words
A table calculation method, in which result data is mathematically calculated for a plurality of cells which are arranged either in a direction of rows or in a direction of columns, comprising the steps of: defining a location and size for each of said plurality of cells by using elements of a matrix structure which is formed by extending all horizontal and vertical ruled lines that define said plurality of cells, wherein elements of the matrix structure have associated calculation data and wherein the location and size for at least one cell of the plurality of cells is defined by a plurality of elements of the matrix structure; and calculating the result data from the plurality of cells, wherein mathematical calculations including the at least one cell utilize calculation data associated with only one of the plurality of elements of the matrix which define the at least one cell.
Claim 3
Dependent Claim
53 words
A method according to claim 1, wherein the at least one cell is defined by elements of the matrix from more than one row of the matrix and wherein the step of calculating the result data comprises calculating the result data for each row using the only one of the plurality of elements.
Claim 4
Dependent Claim
57 words
A method according to claim 1, wherein the at least one cell is defined by elements of the matrix from more than one row of the matrix and more than one column of the matrix, and wherein the step of calculating the result data comprises calculating the result using the only one of the plurality of elements.
