아래코드 좀 봐주세요

이대로 하면 아래처럼 글이 깨지고 엑셀형태로 출력이 안되요 

<?
$sExcelFileName = "bogo" . date("Y") . "-" . date("m") . "-" . date("d") . ".xls";
header( "Content-type: application/vnd.ms-excel" );
header( "Content-type: application/vnd.ms-excel; charset=euc-k");
header( "Content-Disposition: attachment; filename = '$sExcelFileName'" );
header( "Content-Description: PHP4 Generated Data" );

include_once('../../../common.php');

?>

<table border="0">
 <tr>
     <th>성명</th>
     <th>연령</th>
     <th>회사명</th>
     <th>성별</th>
     <th>참관일</th>
 </tr>   
<? $bo_table = 'bogo';
$write_table = "g5_write_{$bo_table}";
$sql = " select * from $write_table";
$result = sql_query($sql);
while ($row = sql_fetch_array($result))
{ ?>
 <tr>
     <td style="mso-number-format:\@"><?=$row['wr_1'];?></td>
     <td style="mso-number-format:\@"><?=$row['wr_2'];?></td>
     <td style="mso-number-format:\@"><?=$row['wr_3'];?></td>
     <td style="mso-number-format:\@"><?=$row['wr_4'];?></td>
     <td style="mso-number-format:\@"><?=$row['wr_5'];?></td>
     </tr>
  </table>  
<? }?>
