A common requirement when displaying large lists of data is to be able to apply styling depending on the contents of the cell. In Microsoft Excel this feature is presented as Conditional Formatting in the Tools menu in Office 97 through 2003 and in the Home tab in the Styles palette in Office 2007.
In General Interface applications, this sort of formatting or coloring of data is achieved using fragments of XSL style sheets known as value templates. Columns of a Matrix component have a property field called value template where XSL can be placed to affect the output during runtime. Value templates are discussed in detail in Chapter 8, "Advanced Features of Matrix."
