The Styles Pane
The styles pane lets you quickly apply predefined formatting to tables in a spreadsheet.
Table styles define such attributes as color, text size, and cell border formatting of table
cells.
To apply a table style, simply select the table and click a style in the Styles pane.
Switching from one table style to another takes only one click.
See “Using Table Styles” on page 79 for details.
