生成 HTML 以并排放置来自 PHP 的两个表

Question

我想在 HTML table 中并排显示两个 table（均按不同的列排序）。尝试：

 <tbody>
   <td>
     <?php
        require_once "db_data.php";
        $bids_results = $mysqli->query("SELECT bid_volume, bid FROM apple_bids ORDER BY bid DESC");
        while($bids = $bids_results->fetch_array()) {
          echo "<tr>\n\t<td>"
          . $bids['bid_volume']
          . "</td>\n\t<td>"
          . $bids['bid']
          . "</td>\n</tr>\n";
        }
        $bids_results->close();
     ?>
   </td>    
   <td>     
     <?php                          
       $offers_results = $mysqli->query("SELECT offer_volume, offer FROM apple_offers ORDER BY offer DESC");
       while($offers = $offers_results->fetch_array()) {
         echo "<tr>\n\t<td>"
         . $offers['offer']
         . "</td>\n\t<td>"
         . $offers['offer_volume']
         . "</td>\n</tr>\n" ;
       }
       $offers_results->close();
       $mysqli->close();    
     ?> 
   </td>  
 </tbody>

但出于某种原因，第二个 table 显示在第一个下方。如果我将两个 <td> 放在 <tbody>

下面的一个 <tr> 中，也会发生同样的情况

Answer 1

试试这个标记：

<table>
     <tr>
          <td>
               <!-- PHP output here -->
          </td>
          <td>
               <!-- PHP output here -->
          </td>
     </tr>
</table>

Answer 2

您真的不需要使用 tbody，因为它会由浏览器生成。使用您的代码，正确的 table 结构将类似于以下内容：

<table>
    <tr>
        <td>
            <table>
                <?php require_once "db_data.php"; $bids_results=$ mysqli->query("SELECT bid_volume, bid FROM apple_bids ORDER BY bid DESC"); while($bids = $bids_results->fetch_array()) { echo "            
                    <tr>
                        <td>" . $bids['bid_volume'] . "</td>
                        <td>" . $bids['bid'] . "</td>
                    </tr>"; } $bids_results->close(); 
                ?>
            </table>
        </td>
        <td>
            <table>
                <?php $offers_results=$ mysqli->query("SELECT offer_volume, offer FROM apple_offers ORDER BY offer DESC"); while($offers = $offers_results->fetch_array()) { echo "
                    <tr>
                        <td>" . $offers['offer'] . "</td>
                        <td>" . $offers['offer_volume'] . "</td>
                    </tr>" ; } $offers_results->close(); $mysqli->close(); 
                 ?>
            </table>
        </td>
    </tr>
</table>
