You can customize the appearance of cells by defining a named style. You can do this within the Spread Designer using the NamedSyle Collection Editor. This editor is launched from the Properties window by first selecting the Spread and then clicking on the button in the NamedStyle property. This property is under the Appearance section. This figure shows the editor with a named style added.

This editor allows you to edit various properties associated with a style that you define. Click Add to start a new style and define the properties of that style, including the name. When you are done, click OK.

For more information about styles and default styles, refer to Creating and Applying a Style for Cells in the Developer’s Guide.
