尝试这个：（完全动态...）

<?php
$host    = "localhost";
$user    = "username_here";
$pass    = "password_here";
$db_name = "database_name_here";

//创建连接
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$connection = mysqli_connect($host, $user, $pass, $db_name);

//从数据库获取结果
$result = mysqli_query($connection, "SELECT * FROM products");

//显示属性
echo '<table class="data-table">
        <tr class="data-heading">';  //初始化表格标签
while ($property = mysqli_fetch_field($result)) {
    echo '<td>' . htmlspecialchars($property->name) . '</td>';  //获取字段名称作为表头
}
echo '</tr>'; //结束tr标签

//显示所有数据
while ($row = mysqli_fetch_row($result)) {
    echo "<tr>";
    foreach ($row as $item) {
        echo '<td>' . htmlspecialchars($item) . '</td>'; //获取项目
    }
    echo '</tr>';
}
echo "</table>";

先获取数据，然后稍后显示。

<?php
$con = mysqli_connect("localhost","peter","abc123","my_db");
$result = mysqli_query($con,"SELECT * FROM Persons LIMIT 50");
$data = $result->fetch_all(MYSQLI_ASSOC);
?>

<table border="1">
  <tr>
    <th>Firstname</th>
    <th>Lastname</th>
  </tr>
  <?php foreach($data as $row): ?>
  <tr>
    <td><?= htmlspecialchars($row['first_name']) ?></td>
    <td><?= htmlspecialchars($row['last_name']) ?></td>
  </tr>
  <?php endforeach ?>
</table>
