When horizontalScrollPolicy is "auto" or "on", as the columns scroll, the columns are always left-justified and any remaining space is given to the last column. I don't think there is any reasonable way to get around this restriction. To prevent swapping of the last column, you might have to catch the event for when columns get re-ordered and guarantee that the empty column is the last column.
