title: How to set dfferent fixed columns datatable
body: <p>I would like to set fixed columns on scroll with data tables, say I have a column at index 1,10,15. On horizontal scroll, I need to be able to set those as fixed. At the moment I am only able to set only the first column to be fixed.</p>
  
  <ol>
  <li><p>Work for the first column</p>
  
  <pre><code>$('#example').DataTable( {
  fixedColumns: true
  </code></pre>
  
  <p>} );</p></li>
  <li><p>Works for the first two columns</p>
  
  <p>$('#example').DataTable( {
              fixedColumns: {
                  leftColumns: 2
              }
          } );</p></li>
  </ol>
