White space in front of html table wrongly produce verbatim block

 <table border="1" width="50%">
   <tr align="center">
     <td>i</td>
     <td>1</td>
     <td>2</td>
     <td>3</td>
     <td>4</td>
   </tr>
   <tr align="center">
     <td>j</td>
     <td>A</td>
     <td>B</td>
     <td>C</td>
     <td>D</td>
   </tr>
 </table>
