如何删除指定的单元格～～
<script>
var i=0
function Add()
{

var table = document.getElementById( "table ");
var row = table.insertRow();
var cell = row.insertCell();
//alert(i);
if (i <=4){
cell.innerHTML = ' <a style=COLOR: #FF0000 href=javascript:del()> 删除 </a> '+i+ ' <input type= "text " name= "aa "> ';
(++i);
//alert(cell.innerHTML);
return true;
}
if (i> 4) {
alert( "对不起，最多只能加5行！ ");
return false;}

}


function del()
{
var table = document.getElementById( "table ");
//if (i > 0)
//{
i= i - 1 ;
table.deleteRow(0)
//}
}

</script>

<a href= "# " onClick= "Add() "> + </a>
<table id= "table " border= "0 ">
</table>
就是我指定删除标号为1的就删除1单元格，删除标号为2的就删除2单元格。现在删除后的标号是错的。

用delete(index)方法就可以了
-------------------------------
function delCells(arg){
var oTrs = document.getElementsByTagName( "tr ");

oTrs[0].deleteCell(arg);
}
-------------------------------
