Defining Table Elements
Now you’ll practice resizing your new table and adding a header column, a header row,
a footer row, and a table name.
To resize your table by adding columns and rows:
1 Click inside the table so that the reference tabs are visible.
2 To add a row, click the arrow near any row’s reference tab to display its pop-up menu,
and then choose Add Row Above or Add Row Below.
3 To add a column, click the arrow in any column’s reference tab to display its pop-up
menu, and then choose Add Column Before or Add Column After.
Later you’ll learn other techniques for adding rows and columns.
