Use footer rows when you want to draw attention to the bottom rows of a table. Footer rows are formatted so that they stand out from the other (body) rows. A footer row consists of the bottommost cell in each column.
You can use as many as five footer rows. To format a footer to span columns, merge the footer cells as Merging Table Cells describes.
To add footer rows, first select a table.
Click Inspector in the toolbar, click the Table inspector button. In the Table inspector, click Table, and then choose the number of footer rows from the Headers & Footer pop-up menu.
Choose Format > Table > Footer Rows > n (the number of footer rows) from the submenu.
Delete footer rows as you would delete any rows. For details, see Deleting Table Rows and Columns.
