Ecco, l'ho fatto io per te:
codice:
<table width="600" border="1" cellpadding="3" cellspacing="0" bordercolor="000000">
  <tr>
    <td width="200" height="50">ID</td>
    <td width="200">NOME</td>
    <td width="200">COGNOME</td>
  </tr>
<?PHP
$i = 1;
for ($count = 0; $count < 11; $count++)
   {
      echo "<tr>\n
              <td height=\"50\">" . $count . "</td>\n
              <td>Nome " . $count . "</td>
              <td>Cognome " . $count . "</td>
            </tr>";
      if ($i % 3 == 0)
        {
	   echo "</table>\n
<table width=\"600\" border=\"1\" cellpadding=\"3\" cellspacing=\"0\" bordercolor=\"000000\">\n
                 <tr>\n
                   <td width=\"200\" height=\"50\">ID</td>\n
                   <td width=\"200\">NOME</td>\n
                   <td width=\"200\">COGNOME</td>\n
                 </tr>\n";
        }
      $i++;
   }
?>
</table>
