Table width overshoots container div

I have a div with:

position: absolute;
margin: 0px;
left: 0px;
right: 0px;
top: 58px;
bottom: 0px;
height: 439px;
width: 880px;
z-index: 1;
visibility: visible;
display: block;

It contains a div and a table. The table tag had width=100%, cellspacing=0 and cellpadding=0.

When I see this in Firefox with Firebug I can see that the table goes beyond the div boundaries. How do I make the table width exactly 100% of the div. In another question asked on this site i saw that the border-collapse:collapse; in the CSS could cause this behavi开发者_JAVA百科our. Hence I have removed that with no effect!

Any help would be appreciated! Thanks

In the fiddle below I modified width to 500px to see the whole div and Chrome/FF debugger shows no problem at all.
