If you want the columns to be an exact size, set the minimum and maximum column widths and call resetColumnWidths() or set the resize policy to FIXED. The preferred width is exactly that, the width that the columns should attempt to maintain if they can. When the resize policy is set to FILL_WIDTH, the table will update the column widths on every page load. When it is set to anything else, you must update the width manually (although that is probably a bug). Either way, the preferred width is not guaranteed, but the minimum and maximum widths are.
