Space between two html table cells

i am working in VS2012.
Hi, Here is my table details
<table style="clear: both; border:0;"> <tr> <td style="float:left;margin:0;background-color:green;width:250px;height:50px;border:0;"> $50</td> <td style="float:left;margin:0;background-color:lightgreen;width:250px;height:50px;border:0;">$100</td> </tr> </table>
if you run this aginat IE9/8 i could see the gap between two cells. whereas in Chrome and firefox it is good. How can i get rid of the while space between two cells in IE. 
since i am using float:left it should not have gap between two cells. any sugestions.
