  <p>The following square should contain exactly two bands, one yellow, one lime, with no red visible.</p>
  <table>
   <tr>
    <td class="test">
     <div class="a">
      <div class="aa"></div>

    <td class="control">

     <div class="b"></div>

   </tr>
  </table>
  <p>This test is meaningless if you don't pass <a href="margin-collapse-118">test 118</a>.</p>
