After you apply a table or cell style, you can override any of its settings. To override a table style, you can change options in the Table Options dialog box. To override a cell, you can change options in the Cell Options dialog box or use other panels to change the stroke or fill. If you select a table or cell that has an override, a plus sign (+) appears next to the style in the Styles panel.
You can clear table and cell overrides when you apply a style. You can also clear overrides from a table or cell to which a style has already been applied.
