Email template background image in Outlook Client

Working with email template is really painful. In the era of HTML5, CSS3 and Javascript, we still need to work in table design because of email clients. Here I am concentrating about the Outlook email client where the background image don't work traditional.

If we want to put a background image in a table row then we need to code as following

<tr class="back" style="height: 38px; background: url(imagepath) no-repeat;">
 
 <td width="70%" style="height: 38px; padding: 0 10px;">
  Cell text
 </td>
 
</tr>
