title: Hide column present in JSON of DataTable with server side processing
body: <p>I followed this post: <a href="https://stackoverflow.com/questions/3531438/jquery-datatables-server-side-processing-using-asp-net-webforms">DataTable: Server Side Processing in ASP.Net</a><br>
  I am using this code to initialize DataTable:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      $(function () {
          $('#example').dataTable({
              'bProcessing': true,
              'bServerSide': true,
              'sAjaxSource': '/data.ashx'
          });
      });
  &lt;/script&gt;
  </code></pre>
  
  <p>My JSON is something like this:</p>
  
  <pre><code>{    
   "iTotalRecords": "57",
   "iTotalDisplayRecords": "57",
   "aaData": [
    [
       "id001",
       "Name001",
       "Addr001",
    ],
    [
       "id002",
       "Name002",
       "Addr002",
     ]
    ]
  }
  </code></pre>
  
  <p>I want to achieve same as below:</p>
  
  <pre><code>&lt;table id="datatable"&gt;
     &lt;thead&gt;...&lt;/thead&gt;
     &lt;tbody&gt;
       &lt;tr id="id001"&gt;
          &lt;td&gt;Name001&lt;/td&gt;
          &lt;td&gt;Addr001&lt;/td&gt;
       &lt;/tr&gt;
       &lt;tr id="id002"&gt;
          &lt;td&gt;Name002&lt;/td&gt;
          &lt;td&gt;Addr002&lt;/td&gt;
       &lt;/tr&gt;
  
       .
       .
     &lt;/tbody&gt;
   &lt;/table&gt;
  </code></pre>
  
  <p><strong>NOTE:</strong><br>
  To assign the id to <code>&lt;tr&gt;</code> I am using:</p>
  
  <pre><code>"fnRowCallback": function( nRow, aData, iDisplayIndex, iDisplayIndexFull) {
       $(nRow).attr("id",aData[0]);
       return nRow;
  }
  </code></pre>
  
  <p>But it is not hiding the <code>ID</code> column.
  Please help.  </p>
  
  <p><strong>Update:</strong>
  I found a perfect solution for my problem.<br>
  I must create my JSON as below   </p>
  
  <pre><code> {    
   "iTotalRecords": "57",
   "iTotalDisplayRecords": "57",
   "aaData": [
    [         
       "0":"Name001",
       "1":"Addr001",
       "DT_RowId": "id001",
    ],
    [        
       "0":"Name002",
       "1":"Addr002",
       "DT_RowId": "id002",
     ]
    ]
  }
  </code></pre>
