Con IE e Firefox, il layout a 3 colonne che uso io, con con banner di testa, barra di navigazione e piè di pagina, si vede bene!
Codice:
<html>
<body>
<table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="100%" height="27"valign="top"><table width="100%" border="1" cellpadding="1" cellspacing="1">
<tr>
<td width="100%" align="center" valign="top">Banner di testa</td>
</tr>
</table></td>
</tr>
<tr>
<td valign="top"><table width="100%" border="1" cellpadding="1" cellspacing="1">
<tr>
<td width="100%" align="center" valign="top">Barra di navigazione</td>
</tr>
</table></td>
</tr>
<tr>
