Display multiple youtube videos in one frame using iframe

You  may not want to embed a lot of  YouTube videos in one post using YouTube embed function. You can use iframe  to display multiple YouTube videos in a frame to save space.
Below is the same code, result displayed after the code:

<table align="center" border="1" cellpadding="0" cellspacing="0" style="background: #52C9CB; border: #64f1f3 1px solid; color: #555555; text-align: center; width: 600px;"><tbody>
<tr>
<td><a href="http://www.youtube.com/v/4oSCuEtxRK8" target="frame138">Part 1</a></td>
<td><a href="http://www.youtube.com/v/y7ae_cZahPs" target="frame138">Part 2</a></td>
<td><a href="http://www.youtube.com/v/IUCEEh-ASH8" target="frame138">Part 3</a></td>
<td><a href="http://www.youtube.com/v/W1zaEiZawsI" target="frame138">Part 4</a></td>
<td><a href="http://www.youtube.com/v/ZNqAOzgS370" target="frame138">Part 5</a></td>
 <td><a href="http://www.youtube.com/v/ZNqAOzgS370" target="frame138">Part 6</a>
</td>
 </tr>
</tbody></table>
<iframe height="600" name="frame138" src="http://www.youtube.com/v/4oSCuEtxRK8" width="100%"></iframe>

Tips:
1. YouTube videos address format  should be similar to http://www.youtube.com/v/4oSCuEtxRK8

2.  Target name and iframe  name (here is frame138) should be the same in one post, but should be different for different posts.
