• Table.php: (application\controllers\Table.php)

<?php

class Table extends CI_Controller {
	public function __construct() {
		parent::__construct();
	}

	public function index() {
		$data = [
			0	=> [
				'level1'	=> 'System',
				'level2'	=> 'System Apps',
				'level3'	=> 'System Env',
				'info'		=> 'App Test',
				'name'		=> 'Foo'
			],
			1	=> [
				'level1'	=> 'System',
				'level2'	=> 'System Apps',
				'level3'	=> 'System Env',
				'info'		=> 'App Memory',
				'name'		=> 'Bar'
			],
			2	=> [
				'level1'	=> 'System',
				'level2'	=> 'System Apps',
				'level3'	=> 'System Env',
				'info'		=> 'App Details',
				'name'		=> 'Foobar'
			],
			3	=> [
				'level1'	=> 'System',
				'level2'	=> 'System Apps',
				'level3'	=> 'System Env2',
