title: Can I use row.add as the InvokeCommand method?
body: <p>In Drupal 8 I want to add a new row to my table in an ajax callback.</p>
  
  <pre><code>   $jQuery=new InvokeCommand('#scanned-vouchers', 'row.add', 
      array('','','','','',''));
     $ajax_response-&gt;addCommand($jQuery);
  </code></pre>
  
  <p>1) The docs say InvokeCommand supports simple jQuery commands e.g. adClass() etc. if row.add is acceptable how go I pass in the column values via argument 3?</p>
  
  <p>2) If not, what other approach can I use to add a row to the table in the ajax callback bearing in mind  I am using jQuery Databale?</p>
  
  <p>TIA</p>
