Border-spacing problem in product listing

[No Posers Please!]

I am just about ready to go live with my shop except for this last problem which is stopping me.

 

I had been testing my shop in Opera, but when I tested it in Internet Explorer the product listing looks different, it's lacking the spacing between each cell in the product listing.

Obviously there's a black frame around the product listing in the Opera screenshot, but don't mind that, that's just me testing.

 

By altering the following code in stylesheet.css I am able to remove the spacing in Opera and make them identical (without spacing).

 

TABLE.productListing {
 border: 2px;
 border-style: solid;
 border-color: #000000;
 border-spacing: 1px;

 

I just turn the border-spacing to zero. But that's the opposite of what I want. I want border-spacing in Internet Explorer as well.

 

Please help!
