Try Implementing this in your td:
<table border="2px">
   <tr>
     <td data-toggle="tooltip" data-placement="bottom"
       title="" data-original-title="Tooltip on bottom"
       class="red-tooltip">Tooltip on bottom
     </td>
   </tr>
</table>

You can use jQuery Plugin or pure css based customised tooltip.
one of the way is below mentioned.
**Include**
jQuery 
 **Inside td keep like this**
    <a href="#" data-toggle="tooltip" data-placement="bottom"
       title="" data-original-title="Tooltip on bottom"
       class="red-tooltip">#487105 CLASSIC LOOSE RD124473 ENGINEERED 2X1-</a> 
**CSS**
.red-tooltip + .tooltip > .tooltip-inner {background-color: #f00;}
**JS**
$(document).ready(function(){
    $("a").tooltip();
});
