               var foot = $("#example").find('tfoot');

                    if (!foot.length) foot = $('<tfoot id="tfoot">').prependTo("#example"); 

                 $('#example thead tr ').each(function (id,text) {
                 $('#example thead').append(text);  
                                   });  

                 $('#example tfoot').append("<tr></tr>");

                    if(id!==0)

                    $('#example tfoot tr').append("<th>"+text.getAttribute('aria-label').split(':')[0]+"</th>");
