body: <p>How can I show and hide columns in datatable.js you see I can enable and disable it BUT the problem is my datable is binded in AJAX source so it automates requests each time I show
  and hide a column.</p>

  <pre><code>$(".table-dash1").dataTable().fnSetColumnVis(0, false);
  </code></pre>
