Select table or cell borders to change their appearance or move them within the table. You can select entire table borders or individual cell borders (segments). You can select multiple borders segments, too, making it easy to change the appearance of several at once.
After a table cell is selected, holding the pointer over a border makes it appear to straddle the line; this appearance tells you that if you click, you’ll select a border or border segment. A simple rule of thumb is to click to select a table and click a second time to select a border, and then click a third time to select a border segment.
Select a table or table cell and click the border selection button in the format bar.
Choose the set of borders that you want from the pop-up menu.
To select a different segment (or only a single segment if two are selected), hold the pointer over the segment you want until it changes to a set of parallel lines, and then click the border to select it.
