<table id= "tabTest ">
<tr>
<td> 1 </td>

<tr>
<td> 4 </td>
<td> 5 </td>
<td> 6 </td>

<tr>
<td> 7 </td>
<td> 8 </td>
<td> 9 </td>
</tr>
</table>
<script type= "text/javascript ">
<!--
var oTable = document.getElementById( "tabTest ");
var colCells = oTable.cells;
for (var i=0; i <colCells.length; i++)
{
colCells[i].onmouseover = function ()
{
if (this.style.border == " ")
{
var oTable = this.parentNode.parentNode.parentNode;
for (var i=0; i <oTable.cells.length; i++)
{
oTable.cells[i].style.border = "1px solid red ";
}
};
}
}
//-->
</script>
