title: How to enable search for hidden column in datatable?
body: <p>I have table which contains a <code>Name</code> column but I don't want to show that column in the table but I need to add a search filter on it. </p>
  
  <p>I tried using the below, but In this case the column and textbox of search filter both are not showing. </p>
  
  <pre><code>{
      "sName": "Name", 
      "bVisible": false, 
      "bSearchable": true
  }
  </code></pre>
  
  <p>When I set <code>"bVisible": true</code> then the text box of filter and column both are showing and also the search works fine. </p>
  
  <p>I am using below code to display column filter.</p>
  
  <p>HTML For Filter:</p>
  
  <pre><code>&lt;div class="col-xs-12 col-sm-6 col-md-4"&gt;
       &lt;div class="form-group"&gt;
            &lt;label class="col-sm-5 control-label"&gt;Customer Name &lt;/label&gt;
                   &lt;div class="col-sm-7" id="serName"&gt;&lt;/div&gt;
        &lt;/div&gt;&lt;!-- form-group --&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>HTML for Table :</p>
