PowerPoint enables you to apply a variety of formats and borders to your tables, including the capability to do the following:
Apply different styles, widths, and colors
Insert and delete rows and columns
Merge and split cells
Align cell text to the top, bottom, or center
You'll want to use the Tables and Borders toolbar to access PowerPoint's table formatting options. If this toolbar doesn't currently appear, you can open it by clicking the Tables and Borders button on the Standard toolbar or by selecting View, Toolbars, Tables and Borders. Table 4.1 lists the buttons on this toolbar.
