   *
   */
  makeSortable: function(table) {
    if (table.getElementsByTagName('thead').length == 0) {
      // table doesn't have a tHead. Since it should have, create one and
      // put the first table row in it.
      the = document.createElement('thead');
 =>   the.appendChild(table.rows[0]);
      table.insertBefore(the,table.firstChild);
