[ic] Listing all product groups @ categories in a table

[Sergei Voyakin]

How would I go about listing all product groups in a table similar to this:
<table>
<tr>
<td>Product Group 1</td>
<td>Product Group 2</td>
</tr>
<tr>
<td>Category 1 for Product Group 1, Category 2 for Product Group 1, Category 
3 for Product Group 1</td>
<td>Category 1 for Product Group 2, Category 2 for Product Group 2, Category 
3 for Product Group 2</td>
</tr>
</table>

There are lots more product groups & categories for each product group, but 
i just want to list 3.
I can loop through all the Product groups and the their respective 
categories, but I just can't get my head around listing them in the next row 
for the table...is this possible?  I was able to just use <BR> between 
prod_group and the list of categories, but it leave a little more room than 
desired between two lines and it does not look as good.

Thanks for your help!
