помогите написать скрипт который выталскивал бы данные из таблице например в формате: @11|12|13|14@21|22|23|24@31|32|33|34

<script type="text/javascript">
<!--
window.onload = function(){
    var tbl = document.getElementById("mytable");
    var tbl_arr_tr = tbl.getElementsByTagName("tr");
    var result_arr = new Array();
    for(var i = 0; i<tbl_arr_tr.length; i++){
        if(tbl_arr_tr[i].getAttribute("valign")!="bottom"){
            var tbl_arr_td = tbl_arr_tr[i].getElementsByTagName("td");
            var result_subarr = new Array();
            for(var j = 0; j<tbl_arr_td.length; j++){
                if(tbl_arr_td[j].getAttribute("headers")=="Name"){
                    result_subarr.push("@");
                }
                else if(tbl_arr_td[j].getAttribute("headers")=="Num"){
                    result_subarr.push(tbl_arr_td[j].innerHTML.replace(/\<(\/?[^\>]+)\>/gm,""));
                }
                else if(tbl_arr_td[j].getAttribute("headers")=="nce"){
                    result_subarr.push(tbl_arr_td[j].innerHTML.replace(/\<(\/?[^\>]+)\>/gm,""));
                }
                else if(tbl_arr_td[j].getAttribute("headers")=="ble"){
                    result_subarr.push(tbl_arr_td[j].innerHTML.replace(/\<(\/?[^\>]+)\>/gm,""));
                }
            }
            result_arr.push(result_subarr);
            result_subarr = undefined;
