Editing Tables

Both the default Condition Table and the default Action Table have one empty row. Click a cell to edit its text contents. Use Tab and Shift+Tab to move horizontally between cells. To add rows and columns to either table, see Appending Rows and Columns.

You set the Truth Table Editor to display only one of the two tables by double-clicking the header of the table to display. To revert to the display of both tables, double-click the header of the displayed table.

Cells for the numbered rows in decision columns like D1 can take values of T, F, or -. After you select one of these cells, you can use the spacebar to step through the T, F, and - values. In these cells you can use the left, right, up, and down arrow keys to advance to another cell in any direction.
