title: Datatables orderable=false directly on table
body: <p>I have several tables, I want to create a single javascript file to manage them
  The problem is they do not have the same number of columns.</p>
  
  <p>So I can not put :</p>
  
  <pre><code>"columnDefs": [{ "targets": [ 3, 4 ], "orderable": false }]
  </code></pre>
  
  <p>because the first table has only 3 columns
  so I would have disabled the ability to sort directly on the table like : </p>
  
  <pre><code>&lt;th data-sort"false"&gt;&lt;/th&gt;
  </code></pre>
  
  <p>It's possible ? How I can do ?</p>
