                height: 50px"></textarea></td>
                <td><textarea class="form-control" rows="3" name="tindakan[]" placeholder="Tindakan Perbaikan dan Pencegahan" 
                style="resize: none; height: 50px"></textarea></td>
                <td><input class="form-control" type="text" name="pic[]" placeholder="PIC" value=""></td>
                <td><input class="form-control" type="date" name="tanggal_pelaksanaan[]" class="picker__table" value=""></td>
              </tr>
            </tbody>
          </table>
