[TxMt] auto HTML table snippet

Is it doable? (I bet it is, but I can't figure it out). I want to create a HTML snippets that transforms a tab delimited table into an HTML table, fo instance, I'd select this:

item_01 item_02 item_03 item_11 item_12 item_13 item_21 item_22 item_23

hit a key combo, and get:

<table> <tr><th>item_01</th><th>item_02</th><th>item_03</th></tr> <tr><td>item_11</td><td>item_12</td><td>item_13</td></tr> <tr><td>item_21</td><td>item_22</td><td>item_23</td></tr> </table>

I guess my biggest problem is to figure out how to get it to work with any number of row and column...

Any help much appreciated... Thanks!
