<p>Gradually change the border-spacing property from 2px to 20px then back:<p>
<table id="myTABLE">
  <tr>
    <th>Name</th>
    <th>Age</th>
  </tr>
  <tr>
    <td>Emil</td>
    <td>9</td>
  </tr>
  <tr>
    <td>Tobias</td>
    <td>7</td>
  </tr>
  <tr>
    <td>Linus</td>
    <td>2</td>
  </tr>
</table>

<p>The border-spacing is <em>animatable</em> in CSS.</p>
<p><b>Note:</b> CSS Animations do not work in Internet Explorer 9 and earlier versions.</p>
