Zabi -
Usually you have something like the code below that makes up your table or cell.
Paste the bold red portion of it into the <TD tag. It should look like the code below. Change the green portion of the code to change the colors. You can use a hex code (ie: #FF6000) or use primary text colors (ie: red, blue, lightblue...)
=============================================
<TABLE width="200" border="1" cellspacing="0" cellpadding="0">
<TR>
&lt;TD style="width:100%; background-color:<font color=green>lightblue</font id=green>"
<font color=red><b>onMouseover="this.style.backgroundColor='<font color=green>yellow</font id=green>';"
onMouseout="this.style.backgroundColor='<font color=green>lightblue</font id=green>';"&gt;</b></font id=red>
Watch me get scared!
&lt;/TD&gt;
&lt;/TR&gt;
&lt;/TABLE&gt;
=============================================
I hope that helps you out some.

Hey Zab-
I'm pretty sure i understand what you are wanting now. However, I can only get it to change the row color. Try this code that I found below. Maybe it will work for you somehow or you can change it a little bit. I dont have time to try and reconfigure it right now. Good Luck!
