Changing verticle tables to horizotial tables?

Hi I have this code, but it's listing the tables in a vertical formart. How can make this display in a horizontal format?

  <td width="165" valign="top" ><table width="160" border="0" align="center" cellpadding="2" cellspacing="0">

      <?php $latest=mysql_query (" select * from xcd_listing where sold='No'  order by time DESC limit 4 ");
 while($row=mysql_fetch_array($latest)){
$make_model=$row[45]."-".$row[46];
if ($row[26]!="")  {$thumb=$row[26];}
elseif ($row[27]!="") { $thumb=$row[27];}
elseif ($row[28]!="") { $thumb=$row[28];}
elseif ($row[29]!="") { $thumb=$row[29];}
elseif ($row[30]!="") { $thumb=$row[30];}
elseif ($row[31]!="") { $thumb=$row[31];}
elseif ($row[32]!="") { $thumb=$row[32];}
elseif ($row[33]!="") { $thumb=$row[33];}
elseif ($row[34]!="") { $thumb=$row[34];}
elseif ($row[35]!="") { $thumb=$row[35];}
else $thumb="no_pic.png";
if($row['year']!="") {$Year=$row['year'];} else {$Year="N/A";}
if($row['price']!="") {$Price=$row['price'];} else {$Price="N/A";}
$cid=$row[0];
if ($Html_Url=="Yes") { $curl="details"."-".$cid.".html";}
else {$curl="details.php?car=".$cid;}
?>
      <tr>
        <td align="center" valign="top" ><table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" >
              <tr>
                <td align="center" nowrap="nowrap" class="separator"><a href="details.php?car=<?php echo $row['v_id'];?>"><strong><?php echo $make_model;?><br />
                  </strong></a><a href="<?php echo $curl;?>"><img src="listing_images/thumb/<?php echo $thumb;?>" alt="<?php echo $make_model;?>" border="0" align="middle" /></a><br />
                  <?php echo L_YEAR,"-", $Year; echo "<br>",L_PRICE,"-<span class=\"verdana_12_red\">", $Price,"</span>";?></td>
              </tr>
          </table></td>
      </tr>
      <?php }?>
    </table></td>
