Answer 1

你刚拼错了。

如下所示检查可能有所帮助。

public function index()
{
     $data['user_list'] = $this->data_Model->Get_Data();  // Use data_model instead Data_model
     $this->load->view('data_view', $data);
}

Answer 2

   Please try this code it will help you. This is controller code

   class Test extends CI_Controller { 

     function __construct() { 
      parent::__construct(); 
      $this->load->helper('url'); 
      $this->load->database(); 
    } 

   public function view(){

     $this->load->model('Test_model');
     $stud_data = $this->Test_model->view();
     $data['data'] = $stud_data->result();
     $this->load->view('Display', $data); 
  }
 }

 This is view part

   <!DOCTYPE html> 
    <html lang = "en"> 
    <body> 
     <table>
       <tr>
        <th>Id</th>
        <th>Name</th>
         <th>Email</th>
        <th>Password</th>
        <th>Edit</th>
        <th>Delete</th>
      </tr>
      <?php
       foreach($data as $key){ ?>
      <tr>
       <td>
          <?php echo $key->id ?> 
       </td>
       <td>
          <?php echo $key->name ?> 
       </td>
       <td>
          <?php echo $key->email ?> 
       </td>
       <td>
          <?php echo $key->password ?> 
       </td>
       <td>
           <a href="#">Edit</a>
       </td>
       <td>
           <a href="#">Delete</a>
       </td>
     </tr>
      <?php } ?>
     </table>
    </body>
    </html>
