Yes: Don't use HTML elements like you did!  - This is a typical scenario for
dataWrap.
You can do it like this:

temp.bildRechts = COA
temp.bildRechts {
  stdWrap.dataWrap (
    <table cellpadding="0" cellspacing="0" class="rechtsBox">
        <tr><td>
        <p class="illuheader">
            {page:title}
        </p>
        </td></tr>
        <tr><td>
            |
        </td></tr>
    </table>
  }
 stdWrap.required = 1
 10 < styles.content.getRight
}

Though I am not sure if "required" works here, since it might consider the
COA as "not empty" due to the page:title inside the dataWrap.
If this is the case you can use numRows like described before in this
thread.
