A user can move a tier over others by grabbing it in the middle (not the border) with the mouse and dragging it vertically. When dropped the tier will take a new position in the stack of tiers and other tiers will be pushed down (or up) to accommodate the dropped tier's new position. All tiers retain their pre drag height. Scrolling is not instigated. Maybe it should be.
JTable allows columns to be shuffled the same way. If a column is moved past the right edge the column can be moved several places of screen (although this is not visible). Open Office Spreadsheet does not allow such shuffling of either rows or columns.
