tabeller - så felter står pænt

Skal foretage ændringer i følgende kode således at alle felterne står pænt, og lige under hinanden. Hvordan gøres dette?

<table width="600" align="center" border="0" cellpadding="0" cellspacing="0">
    <tr>
      <td>Navn</td>
      <td><input type="text" name="Name"></td>   
    </tr>
    <tr>
    <td>Adresse</td>
    <td><input type="text" name="Adress" size="60"></td>
  </tr> 
  </table>
