Advanced help – conditionnal tag

Hi, i need a pro helper.
How can i show this table if i have the data in the custom value “Content”, and do not show no thing if there is no data.

<table>
    <tr>
      <td>
          <b>Content</b>
      </td>

      <td>
            <?php $values = get_post_custom_values("content"); echo $values[0]; ?>
      </td>
    </tr>
</table>

Thanks for providing the code.
