报错信息：Cannot read property 'mData' of undefined

解决方法：在<table></table>中加上
<table>
<thead></thead>
<tbody></tbody>
</table>

报错信息：Class 'Admin\Controller\mysqli' not found

解决方法：

$conn = new mysqli($servername, $username, $password, $dbname);
mysqli_query($conn,'set names utf8');
if ($conn->connect_error) {
die("error: " . $conn->connect_error);
}

改用：

$conn = mysqli_init();

$conn->options(MYSQLI_OPT_CONNECT_TIMEOUT, 2);//设置超时时间

$conn->real_connect($servername, $username, $password, $dbname);
