Sigo recibiendo esta alerta de error = "Advertencia de tablas de datos (id de tabla = 'tabla_semna'): Se solicitó el parámetro desconocido '1' del origen de datos para la fila 0"

Aquí hay un fragmento de mi código:

  <table id="msnc_table" class="dataTable">
  <thead>
    <tr>
        <th>Doc#</th>
        <th>Date</th>
        <th>Code</th>
        <th>Customer Name</th>
        <th>S/m</th>

    </tr>
 </thead>
 <tbody>
     <tr>
         <td class="dataTables_empty">Loading data from server</td>
     </tr>
 </tbody>
 </table>

   "bProcessing": true,

   "iDisplayStart": 0,
   "iDisplayLength": 11,
   "sAjaxSource": base_url+"raw/raw_ajax/get_mnsc",
