This page describes how to move columns around to change your column arrangement.
A the top of the list is a column header which contains the names for each column. It looks like this:
It is not possible to move the fixed columns on the left. The columns on the right can be arranged any way you like. To move a column simply drag its label in the column header from its present location and drop it in its intended new location. A will appear in the column header before you drop the column label, indicating where it will be inserted. If a does not appear then the column label you are dragging is not over the column header and if you drop it INTERFACE™ will assume that you are trying to remove the column.
