[TxMt] auto HTML table snippet

[Yann B]

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!
