title: Append element to Datatable header
body: <p>What I'd like to do is add a radio button next to the <strong>Search Bar</strong> on my datatable to allow searching by just one column, <strong>Store Number</strong>.</p>
  
  <p>I was referred to drawCallback but I don't believe this does what I expect it to do. All the answers I find seem to be appending elements to rows/cols in the datatable, but not the header itself.</p>
  
  <p>The selector for this header is <code>#store-table_wrapper</code>.</p>
  
  <pre><code>   $('#store-table').DataTable({
          "columnDefs": [{
              "targets": [7, 8],
              "visible": false,
              "drawCallback": function() {
                  $('&lt;input type="radio" name="store-number-filter-selector" /&gt;').appendTo('#store-table_wrapper');
              }
          }]
      });
  </code></pre>
