Remarks
The AutoOutline method uses worksheet formulas to determine how to outline data by columns. Make sure that your worksheet contains summary columns with formulas, based on which the outline will be created. If you did not specify any summary formulas, the columns in a worksheet will not be grouped.
To remove an outline of columns, use the ColumnCollection.ClearOutline method.
