You can change the height and width of individual columns and change the height of individual rows by clicking on the "Set column widths" button on the Edit Table screen.

In the Column Width section, you have the option to define each column width in pixels or percentages. We recommend being consistent in whichever method you select, rather than using both pixels and percentages within the same table. To make a selection, click the appropriate radio button and enter the value.

In the Row Height section, you have the option to define the height of individual rows within your table. You must enter the values in pixels. To define a row height, type the value into the appropriate text box.
