Can't change height of table cell
<p>I'm trying to dynamically change the height of a cell than contains a div.  Now i can change the height of the div, just fine, but when I try the cell, it just doesn't work, yet I get no errors.  Any Ideas on why this doesn't work?</p>

<pre><code>if( df0.checkbox1.checked)
{
    document.getElementById('layerOne').style.visibility = 'visible';
    document.getElementById('layerOne').style.height = 125;
    document.getElementById('eftcell').height = '125px'
}
else
{
    document.getElementById('layerOne').style.visibility = 'hidden';
    document.getElementById('layerOne').style.height = 1; 
    document.getElementById('eftcell').height = '1px'
}
</code></pre>
