Create your own Crud plugin.

Hi, I need help with Create Your Own Plugin. I receive errors when creating a crud, can you help me how to make a crud. I am new to laraship and if I know of laravel, but to adapt to the modules it is difficult for me, in cases such as: making queries, to delete and edit. for example if I make a query from BasrController 

 public function index() { $users = DB::table(\'users\')->get(); return view(\'bars.index\', [\'users\' => $users]); }

  and I list this table, I attach image  

Can you help me with more information ..Thank you
