			<table class="tableform">
					  <tr>
						<td>[xfinput_pole-1]</td>
						<td>[xfinput_opisanie-k-pole-1]</td>
						<td><div onclick="document.getElementById('pole-2').style.display=''">Еще</div></td>
					  </tr>
					  <tr id="pole-2">

						<td>[xfinput_opisanie-k-pole-2]</td>
						<td><div onclick="document.getElementById('pole-3').style.display=''">Еще</div></td>
					  </tr>			
					  <tr id="pole-3">
						<td>[xfinput_pole-3]</td>
						<td>[xfinput_opisanie-k-pole-3]</td>
						<td><div onclick="document.getElementById('pole-4').style.display=''">Еще</div></td>
					  </tr>

						<td>[xfinput_opisanie-k-pole-4]</td>
						<td><div onclick="document.getElementById('pole-5').style.display=''">Еще</div></td>
					  </tr>
