Cell
Properties, Borders tab
Use Cell Borders to display the borders of one or several cells in a special style. Also you can add partial borders to cells that do not display regular borders (hidden cell borders or limb groups).
Note: The chosen style for vertical lines will effect only the right side border of the selected cells.
To display an extra border,
choose an extra line style for the selected
cells' vertical, top and bottom borders.
To return to the default appearance,
choose Default in the line style boxes.
Note: If you choose Default in one of the line style boxes, regular staff borders are displayed, or, if you unchecked the Regular Staff Borders Show check box, no staff borders are displayed at all.
