Unlike paragraph and character styles, table and cell styles do not share attributes, so applying a table style does not override cell formatting, and applying a cell style does not override table formatting. By default, applying a cell style removes formatting applied by any previous cell style, but does not remove local cell formatting. Similarly, applying a table style removes formatting applied by any previous table style, but does not remove overrides made using the Table Options dialog box.

In the Styles panel, a plus sign (+) appears next to the current cell or table style if the selected cell or table has additional formatting that isn’t part of the applied style. Such additional formatting is called an override.
