    table.find('td').filter(function () {
      return $(this).index() === thIndex;
    }).sortElements(function (a, b) {
      return $.text([a]) > $.text([b]) ? inverse ? -1 : 1 : inverse ? 1 : -1;
    }, function () {
      // parentNode is the element we want to move
      return this.parentNode;
    });
    inverse = !inverse;
  });
