ok here is what i found, TD position should not be set to absolute. a work around for me was to wrapp the 2 div in another div container
Code:
 <td style="position:relative;text-align:center;">   
                     <div style="position:absolute;text-align:center;border:1px solid grey;width:100&#37;;height:100%;top:0px;left:0px;">
                        <div class="databar" style="position: absolute; height: 90%; width: 60%; border: thin solid aqua;background:yellow; left: 2px;top:0px;"></div>
                        <div style="position:absolute;left:30%;width:40%;border:1px solid green;height:80%;top:2px; text-align:center; vertical-align: middle;"> 323</div>
                    </div>                
               </td>
