How to: Outline Data Automatically
The example below demonstrates how to outline data automatically using the Worksheet.AutoOutline method.
The Worksheet.AutoOutline method uses worksheet formulas to determine how to group data. Thus, make sure that the worksheet you wish to outline contains summary rows or columns with formulas based on which the outline will be created. If you did not specify any summary formulas, the data will not be grouped.
To remove an outline for the specified worksheet, use the Worksheet.ClearOutline method.
