The ghost of a dragged column is now its header and the cells of the rows in
view, copied once when the drag starts and moved sideways by a transform,
kept within the list; the column dims in place, its cells by one style rule
so no row renders. A built-in column turned on before any reordering takes
its default place again; once the person has an order, a newly shown column
goes at the end.
