SecondarySortColumn

Declaration: ChartBook.Tables[].SecondarySortColumn: integer;
The property SecondarySortColumn determines the column which is used as sorting criterion if two or more elements of the column to be sorted are equal. Please note that the property SecondarySortColumn has only an effect on the interactive sorting (i.e. when the user clicks the heading of a particular column).

Setting SecondarySortColumn to -1 suppresses secondary sorting.
