bGroupColumn:AddColumn() adds a column to the group column. The access bGroupColumn:ColumnList contains a list with all columns that were added to the group column. With the method bGroupColumn:RemoveColumn() a column can be removed from the group again.
So that the column is displayed in the group column, it must be opened (see bBrowser:OpenColumn()) in the bBrowser and the bBrowser must be recalculated with the method bBrowser:Recalculate().
The data columns that are added to the group column must be open side by side in the bBrowser. Data columns are adjacent if they are following one after another in the list bBrowser:ColumnOpenList.
