<?php
$students = array(
    array("name" => "张三", "age" => 20, "gender" => "男"),
    array("name" => "李四", "age" => 21, "gender" => "女"),
    array("name" => "王五", "age" => 19, "gender" => "男")
);

$table = "<table>
            <thead>
                <tr>
                    <th>姓名</th>

            <tbody>";

foreach ($students as $student) {
    $row = "<tr>
