如何通过javascript脚本实现，当前面页上的表格增加一行？？？最好能提供源码，谢了！！！

[fason]

<SCRIPT LANGUAGE=javascript>
function delCol() {
try {
var Elm = event.srcElement;
while(Elm && Elm.tagName != "TR") {
Elm = Elm.parentElement;
}
if(Elm.parentElement.rows.length <= 1) {
alert("无法删除！");
return;
}
Elm.parentElement.deleteRow(Elm.rowIndex);
} catch(e) {
alert("Err 5001:\r\n" + e);
}
}
function addCol(id) {
try {
var oTable = document.getElementById(id);
if(oTable.tagName != "TABLE")
alert("Err 5002");
var oList = oTable.children;
var oTBODY;
for(var i=0;i<oList.length;i++) {
if(oList[i].tagName == "TBODY") {
oTBODY = oList[i];
break;
}
}
var oTR = oTBODY.lastChild;
var newTR = oTR.cloneNode(true);
addId(newTR);
oTBODY.insertAdjacentElement("beforeEnd",newTR);
} catch(e) {
alert("Err 5002:\r\n" + e);
}
}
function addId(node) {
try {
if(!node.hasChildNodes()) {
var prefix = node.getAttribute("id").split("_")[0];
var postfix = node.getAttribute("id").split("_")[1];
postfix = parseInt(postfix) + 1;
node.setAttribute("id",prefix + "_" + postfix);
node.setAttribute("value","");
return;
}
} catch(e) {}
try {
var oList = node.childNodes;
for(var i=0;i<oList.length;i++) {
addId(oList[i]);
}
} catch(e) {
alert("Err 5003:\r\n" + e);
}
}

fason(阿信)，多谢！马上给分！
现在小弟还有一个问题：我插入的行中有一个序号和文本框text，第一行text的默认值为01，那我如何实现在新增行中的序号和文本框中的值累计加1啊？并且要区分文本框的name，请指教，万分感谢！！！

用rows[i].cells[j].children[0]定位文本筐，循环计算或者直接读rows.length

[kingdomzhf]

table.insertRow(-1)
