Remove unwanted space between two html table cells

Hi,

 am working in VS2012.

Hi, Here is my table details

 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. 

 <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>
