A family of Microsoft word processing software products for creating web, email, and print documents.
Make sure that you set the document defaults so that they match the corresponding settings for the Normal style. This is usually an efficient step even if you don't actually use the Normal style much in your documents (and it works because of Word's convoluted hierarchy of styles and formatting). Word will honor settings applied by other styles, even inside table cells.
To access the settings of the Normal style, you can start in the Apply Styles pane (Ctrl+Shift+S). Type in Normal and click Modify. Basic font and paragraph settings are exposed directly in the Modify Style dialog box (and you can click Format > Font and Format > Paragraph, respectively, for more).
To access the document defaults, click the Manage Style icon in the Styles pane (Ctrl+Alt+Shift+S) and go to the Set Defaults tab. The options shown there must match the corresponding options of the Normal style. (Again, this doesn't mean that you are limited to using the Normal style inside tables, only that the settings must match for other styles to be honored by Word.)
