Embedding a YouTube Video in a Table

Hello, I'm trying to embed a YT video in a table the but video doesn't appear in the visual page editor or preview screen. Here's what I'm using: <table style="width: 100%;"> <tbody> <tr> <td>[youtube http://www.youtube.com/watch?v=46lb7hn4ukM]</td> <td style="vertical-align: top;">Shalco U180 - this is placeholder text for this video</td> </tr> </tbody> </table> I tried using the URL in place of the embed code and had the same problem. I would appreciate any suggestions. Thank you.
