Select Move before to move a column or computed column before some other one in the Column sequence list. The column or computed column that will be moved is the one you have selected in the Column sequence list.

From the Move before cascaded menu, select the column or computed column you want the one you selected in the list to be moved before.

If there are no columns or computed columns in the Column sequence list or one is not selected, Move before is not available. The cascaded menu choice that corresponds to the column or computed column you have selected in the list is always not available.
