				DropCellInfo cell = (DropCellInfo)removedIter.next( );
				cell.cell.setHeight( cell.cell.getHeight( ) + maxHeight - cell.leftHeight );
			}
			currentBP += maxHeight;
		}

	protected void removeDropAreaBySpan( int rowSpan )
	{
		int maxHeight = 0;
		Iterator iter = dropList.iterator( );
		ArrayList removedList = new ArrayList();

			DropCellInfo dropCell = (DropCellInfo) iter.next( );
			if ( dropCell.rowSpan == rowSpan )

				removedList.add( dropCell );
