title: DataTables sort icons not showing
body: <p><a href="https://i.stack.imgur.com/eewr3.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/eewr3.png" alt="sort icons do not display on header"></a></p>
  
  <p>I tried hours to solve this problem, can anyone tell me how can I get those icons or tell me how to make a custom CSS file  </p>
  
  <p>files I linked </p>
  
  <pre><code>dataTables.bootstrap.min.css
  </code></pre>
  
  <p>and following script files </p>
  
  <pre><code>    &lt;script src="js/lib/datatables/datatables.min.js"&gt;&lt;/script&gt;
  &lt;script src="js/lib/datatables/cdn.datatables.net/buttons/1.2.2/js/dataTables.buttons.min.js"&gt;&lt;/script&gt;
  &lt;script src="js/lib/datatables/cdn.datatables.net/buttons/1.2.2/js/buttons.flash.min.js"&gt;&lt;/script&gt;
  &lt;script src="js/lib/datatables/cdnjs.cloudflare.com/ajax/libs/jszip/2.5.0/jszip.min.js"&gt;&lt;/script&gt;
  &lt;script src="js/lib/datatables/cdn.rawgit.com/bpampuch/pdfmake/0.1.18/build/pdfmake.min.js"&gt;&lt;/script&gt;
  &lt;script src="js/lib/datatables/cdn.rawgit.com/bpampuch/pdfmake/0.1.18/build/vfs_fonts.js"&gt;&lt;/script&gt;
  &lt;script src="js/lib/datatables/cdn.datatables.net/buttons/1.2.2/js/buttons.html5.min.js"&gt;&lt;/script&gt;
   &lt;script src="https://cdn.datatables.net/buttons/1.5.2/js/buttons.print.min.js"&gt;&lt;/script&gt;
