Applying the Text Format to Table Cells
Use the text format when you want all of a cell's content to be treated as text, even
when it's a number. When a text format is applied to a cell, its value is displayed
exactly as you type it.
To apply the text format:
Select the cell or cells.
Click Inspector in the toolbar, and then click the Table button.
In the Table inspector, click Format.
Choose Text from the Cell Format pop-up menu.
