Question

我正在尝试使用DataTables，但是由于某种原因，它似乎无法正常工作。我正在使用Bootstrap 4，并且需要DataTables中的按钮，以便以后可以导出该表。我想我已经添加了所有我需要的东西，但是没有显示出来。有人知道为什么它没有用吗？该表是从数据库中发布的，它在引导程序中可以正常工作，并且所有信息都可以显示出来，但是当我尝试向其中添加DataTables时，似乎一切都没有改变。

 <?php 
    ini_set('display_errors', 1);
    ini_set('display_startup_errors', 1);
    error_reporting(E_ALL);

    include_once('connection.php');
    if($_SERVER['REQUEST_METHOD'] == "POST" and isset($_POST['someAction']))
        {
            func();
        }
        function func()
        {
          $conn = mysqli_connect("localhost", "root", "", "SportsDB");
        }
    session_start();
    if( !isset($_SESSION['username']) ){ /* Change into role = teacher or admin*/
      header('Location:login.php');
    }

    print_r($_SESSION);
    ?>

感谢您的帮助。我需要在DataTables之前调用jquery。
