Existe-t-il un moyen d'appliquer un style de classe à un seul niveau de balises td?
<style>.MyClass td {border: solid 1px red;}</style>
<table class="MyClass">
<tr>
<td>
THIS SHOULD HAVE RED BORDERS
</td>
<td>
THIS SHOULD HAVE RED BORDERS
<table><tr><td>THIS SHOULD NOT HAVE ANY</td></tr></table>
</td>
</tr>
</table>
