Indicates whether the table or PivotTable style is built-in.
true if the table or PivotTable style is built-in; otherwise, false.
By default, the workbook’s TableStyleCollection collection contains a set of built-in table and pivot table styles similar to Microsoft® Excel®. These styles cannot be modified or removed from the collection. However, you can use a built-in style as a base for creating your own custom style. To do this, access a built-in style by its name or identifier (BuiltInTableStyleId for tables or DevExpress.Spreadsheet.BuiltInPivotStyleId for pivot tables), call the TableStyle.Duplicate method and modify the format settings of the created copy of the built-in style.
