高分：一个老问题，如何从一个table复制到另外一个table

仅供参考:
<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);
}
}
</SCRIPT>

好多分啊*_*,看在这么多分的份上,我就专门写一段代码吧~~~~~
<html>
<head>
</head>
<body>
<script language="javascript">
function chkMe(){
var currObj = event.srcElement;
var tabB = document.getElementById("table_b");
var currCell = currObj.parentNode;
var currRow = currCell.parentNode;
if(currObj.checked)
{
var newRow = tabB.insertRow();
newRow.bgColor="gray";
var newCell = newRow.insertCell();
newCell.innerHTML = currRow.cells[1].innerText;
newCell.id = currObj.value;
}else{
var theRows = tabB.rows;
for(var i=0;i<theRows.length;i++)
{
if(theRows[i].cells[0].id==currObj.value)
tabB.deleteRow(i);
}
}
}
</script>
       表格a:
<table width="80%" border="1" align="center" bordercolor="#000000" id="table_a">

</table>
       表格b:
<table width="80%" border="1" align="center" cellpadding="2" cellspacing="1" bordercolor="#000000" id="table_b">
<tr>
<td>已经选中的学生</td>
</tr>

楼上的正确
还可以用cells[].rows[].innerHTML来返回这一行的html值在另一行中加入即可
用innerHTML来搞定不久行了？？

tr的innerHTML是只读的,你可以试试...
