<script>
function OnMouseOverTd()
{
event.srcElement.parentNode.style.background = "blue";
}
function OnMouseOutTd()
{
event.srcElement.parentNode.style.background = "white";
}
</script>

<table>
<tr>
<td onmouseover=OnMouseOverTd() onmouseout=OnMouseOutTd()>test 1</td>
</tr>
<tr>
<td onmouseover=OnMouseOverTd() onmouseout=OnMouseOutTd()>test 2</td>
</tr>
<table>
