How do I center an image in a table in Outlook

Question

What is the correct inline css to move text or an image center in Outlook. Any time I open it in a browser, it looks great but the bottom image and text always stay left in Outlook. Not sure what else to try. Any help is appreciated

 <table cellpadding="0" cellspacing="0" border="0" width="800" align="left">
     <table align="left" width="800px;">
         <tr width="800px">
             <td><img width="800px;" src="images/ArlingtonPic-edited.png"></td>
         </tr>  
     </table>

     <table align="left" width="800px;">
        <tr width="800px">
           <td width="800px" style="font-size:20px; margin-left: auto; 
               margin-right: auto; text-align: center; vertical-align: middle;">
               <strong>Arlington Concrete Floor Boxes</strong></td>
        </tr>
     </table>

     <table align="left" width="800px;">
        <tr width="800px">
           <td width="350px" style="font-size:16px; padding: -10px 10px 0 10px;">

                 It is <em>REVERSIBLE!</em></p>
                 </ul>
           </td>

           <td width="350px" style="font-size:16px; padding: 0 10px;">

                  our concrete boxes. <br>

           </td>
        </tr>
     </table>

     <table align="left"  width="800px;">
