Change Border Of Some Cell By OnMouseOver Different Cell?

imagine table with 15 rows and 3 columns. If I move mouse over any cell I want some other specific cells to change their borders like with pseudo-class :

example

<style>
.boryellow {border: 3px solid yellow}
.borblue {border: 3px solid black}
</style>

this will work, a cell can change itself

<td name="third" class="boryellow" onmouseover="this.className='borblue'" onmouseout="this.className='boryellow'">cell</td>
even when dealing with empty images - click on link will change border of different element - imgs, but not span or td ...
<a href="#" onclick="document.all.xxx.className='borblue'; document.all['name'].className='borblue';

[code].....

Replacing any element link by "third" or "spanx" will cause stuck ant not executing other actions.
