here's another method:
<style type="text/css">
.foo1 { font-family: arial;
font-size: 9pt;
background-color: green;
text-decoration: none;
color: #000000;
}
.foo2 { background-color: red;
text-decoration: none;
color: #000000;
}
.gee { font-family: arial;
font-size: 10pt; }
</style>
<table cellpadding="5" cellspacing="0" width="600">
<tr class="foo1" onmouseover="this.className='foo2'", onmouseout="this.className='foo1'" >
<td class="gee">more sample text goes here</td>
</tr>
</table>
works in IE6, NS6/7, Mozilla1.4b, but not w/ NS4.x or Opera 6.04
