ABSTRACT:
A document processing apparatus for easily editing a table includes: an input device to input data corresponding to the number of ruled lines to be displayed; position indicating device for indicating a position on a display screen; a display which can display grids on the display screen at regular intervals; an arithmetic computing circuit to arithmetically compute a line interval between a plurality of ruled lines on the basis of the number data which is input from the input device and the position indicated by the position indicating device; and a display controller for controlling the display so as to display the plurality of ruled lines at regular intervals in correspondence to the display positions of the grids on the basis of the result of the arithmetic computation from the arithmetic operating circuit and an interval between the grids. With this apparatus, ruled lines can be drawn or edited by simple operations without exerting any influence on the other cells or lines.
