  54 The following table show how nested tables inherit colors from the wikitable class (here it was renamed "global").
  55 </p>
  56 <table class="global">
  57 <caption>Global table</caption>
  58 <tr>
  59         <th>TH: should have pink bg</th>
  60 </tr>
  61 <tr>
  62         <td>TD: white bg</td>
  63 </tr>
  64 <tr>
  65         <td>
  66                 <table class="nested">
  67                 <caption>Nested table</caption>
  68                 <tr>
  69                         <th>Nested TH: transparent</th>
  70                         <td>Nested TD: transparent</td>
  71                 </tr>
  72                 </table>
  73         </td>
  74 </tr>
  75 </table>
  76
  77 <p>
  78 With child selector we could limit the wikitable styling to the direct childs of the table. Unfortunately, Internet Explorer 6.0 does not support child selector. See <a href="https://bugzilla.wikimedia.org/show_bug.cgi?id=33752">our bug #33752</a>.

  81 <caption>Global table</caption>
  82 <tr>
  83         <th>TH: should have pink bg</th>
  84 </tr>
  85 <tr>
  86         <td>TD: white bg</td>
  87 </tr>
  88 <tr>
  89         <td>
  90                 <table class="nested">

  92                 <tr>
  93                         <th>Nested TH: transparent</th>

  97         </td>
  98 </tr>
  99 </table>
 100 <p><strong>NOTE:</strong>The nested caption keep the green background. The nested table keep the black border. This is because those declarations are global so we did not reset them.</p>
