  • Method and apparatus for modifying a display matrix in a computer window by adding one column or row at a time
    Patent number: 5621876
    Abstract: A method of modifying a display matrix in a matrix display area in a window on a computer display screen. The method includes the steps of displaying data in a matrix format, thereby forming a display matrix in the matrix display area, the matrix display area having a first dimension, and increasing, responsive to a selection of an increase activator, the number of existing columns of matrix cells in the display matrix by adding an additional column of matrix cells to the display matrix. The method further includes the step of computing, using a central processing unit, a computed width of a column of matrix cells in the existing columns of matrix cells if the column of matrix cells is reduced in width to accommodate the additional column of matrix cells.
