如何在PHP中让两个SQL列并排在两个单独的<td>中回显

<?php
// 连接到数据库
$servername = "数据库服务器名";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";

$conn = mysqli_connect($servername, $username, $password, $dbname);

// 检查连接是否成功
if (!$conn) {
    die("连接失败: " . mysqli_connect_error());
}

// 执行SQL查询
$sql = "SELECT column1, column2 FROM your_table";
$result = mysqli_query($conn, $sql);

?>

<!-- 在HTML中显示查询结果 -->
<table>
    <tr>
        <th>列1</th>
        <th>列2</th>
    </tr>
    <?php while ($row = mysqli_fetch_assoc($result)) { ?>
        <tr>
            <td><?php echo $row['column1']; ?></td>
            <td><?php echo $row['column2']; ?></td>
        </tr>
    <?php } ?>
</table>

<?php
// 关闭数据库连接
mysqli_close($conn);
?>
