By default, tables have a header row, but no footer row. You can remove the header row using the row adorner.

To remove a table header

Click the table to reveal the adorners.
Hold your pointer to the left of any row to reveal the row adorner.
Click the arrow button in the center to reveal the row menu.
Select Toggle Table Header. The table header row is removed from the table.
To re-add the table header row, select Toggle Table Header again.

You can turn the footer and detail rows on or off using the Toggle Table Footer and Toggle Table Details menu items. If you put a summary field in a footer row, you can turn off the details to show a summary report.

Note: You can also add or remove a table header or table footer by toggling them in the Table Design Tools Toolbar.
