                            <?php $listaDados = $Usuario->carregaSetores(); ?>
                        </select>
                    </td>

<?php print_r($_POST);?>
             <div>
                <table width="100%" CELLSPACING="0" CELLPADDING="2" BORDER="1" class='tabelaProt'>
                                <thead>
                                        <tr>
                                             <th>Alguma Coisa</th>
                                             <th>Alguma Coisa</th>
                                             <th>Alguma Coisa</th>
                                             <th>Alguma Coisa</th>
                                        </tr>
                                </thead>
                        <tbody>         
  <?php

            //echo "</pre>"; print_r($_indoperacional); exit;
     foreach($exibiRelatorios as $Relatorios){
          echo '<tr>';
          echo '<td align=center>'.$Relatorios.'</td>';
          echo '<td align=center>'.$Relatorios.'</td>';
          echo '<td align=center>'.$Relatorios.'</td>';
          echo '<td align=center>'.$Relatorios.'</td>';

          echo '</tr>';

        //print_r($_parametros);
     }
     ?>
