Question

我有6个表头和6个表数据，但是从图像中可以看到有一个表头间隙，但是如何消除该间隙？有6个表头，但我需要7个表数据才能使其相等……

如下图所示：

为了更加清楚，我将所有td和th的背景设置为黑色（第6和6 td）：

编码：

<table class="table table-bordered" style='padding: 20px 20px;display:table-header-group;table-layout: fixed;'>
        <tr>
            <th>Date</th>
            <th>Time</th>
            <th>Product<th>
            <th>Quantity</th>
            <th>Price</th>
            <th>Payment Method</th>
        </tr>

        <?php

        while($row=mysqli_fetch_array($res)){                    
            echo "<tr>";
            echo "<td>"; echo $row['orderdate']; echo "</td>";
            echo "<td>"; echo $row['ordertime']; echo "</td>";
            /////////////////productname
            echo "<td>";
            echo "<table>";           

            while($row2=mysqli_fetch_array($res2)){

            echo "<tr>";
            echo "<th>"; echo $row2['listingname']; echo "</th>";
            echo "</tr>";
            }

            echo "</table>";
            echo "</td>"; 
            echo "<td>"; echo "qty"; echo "</td>";
            echo "<td>"; echo "price"; echo "</td>";
            echo "</tr>";

            }
        ?>
    </table>

因此，实际上我错过了产品末位的1分之一，谢谢大家的帮助

 <tr>
                        <th>Date</th>
                        <th>Time</th>
                        <th>Product</th>
                        <th>Quantity</th>
                        <th>Price</th>
                        <th>Payment Method</th>
                    </tr>

Answer 2

在您的代码中，您声明6列，但只感觉其中3列。

因此，为了正确处理，您应该在最后一个colspan上添加一个td，例如以下代码：

<table class="table table-bordered" style='padding: 20px 20px;display:table-header-group;table-layout: fixed;'>
    <tr>
        <th>Date</th>
        <th>Time</th>
        <th>Product<th>
        <th>Quantity</th>
        <th>Price</th>
        <th>Payment Method</th>
    </tr>
    <?php

        while($row=mysqli_fetch_array($res)){                    
            echo "<tr>";
            echo "<td>"; echo $row['orderdate']; echo "</td>";
            echo "<td>"; echo $row['ordertime']; echo "</td>";
            /////////////////productname
            echo "<td colspan='4'>";
            echo "<table>";           

            while($row2=mysqli_fetch_array($res2)){

                echo "<tr>";
                echo "<th>"; echo $row2['listingname']; echo "</th>";
                echo "</tr>";
            }

            echo "</table>";
            echo "</td>"; 

            echo "</tr>";

        }
    ?>
</table>
