title: How to display different values on field & table column in grocery crud
body: <p>I want to display different values on field &amp; table column.
  This is my code for dropdown values on field :</p>
  
  <pre><code>public function orders_management()
  {
      try{
          $crud = new grocery_CRUD();
  
          $crud-&gt;set_table('order');
          $crud-&gt;set_subject('Order');
          $crud-&gt;display_as('software_list_fk','Software');
          $crud-&gt;set_relation('software_list_fk','software_list', '{software_name} | {part_number}');         
  
      }catch(Exception $e){
          show_error($e-&gt;getMessage().' --- '.$e-&gt;getTraceAsString());
      }
  }
  </code></pre>
  
  <p>This works for my dropdown values, but I only want to display 'software_name' in table column not 'software name | part_number'.
  How to resolve that problem?
  Thanks in advance</p>
