    <div class="wrap">
        <div id="primary" class="content-area">
            <main id="main" class="site-main" role="main">

                <?php
                $newdb=new wpdb('root','','wpdemo1','localhost');



                $rows=$newdb->get_results("Select * From wp_student");
                if($rows)
                {
                    foreach ($rows as $obj) 
                    {
                        //$path = 'admin.php?page=EditStud&id='.$obj->roll;
                        //$url = admin_url($path);
                        //$id=$obj->roll;
                       ?>

                ?>

            </main><!-- #main -->
        </div><!-- #primary -->
    </div><!-- .wrap -->

        <script>
            jQuery(document).on('click', '.delete', function () {

    }

    add_action('wp_ajax_delete_student', 'delete_student');
    add_action( 'wp_ajax_nopriv_delete_student', 'delete_student');
