How can I increase table [on hold]

How can I increase table columns by "resizableColumns" jquery right to left $("table#demo-table th").resizable({ handles: "e,n", minHeight: thHeight, maxHeight: thHeight,

  resize: function (event, ui) {
    var sizerID = "#" + $(event.target).attr("id") + "-sizer";
    $(sizerID).width(ui.size.width);
  }

});
