[jQuery] wrap some tag around group of table rows for hide and show

[jQuery] wrap some tag around group of table rows for hide and show


within a table, I would like to hide or show a group of rows in a
table. I tried wrapping those rows with a div, then I tried a span.
Neither worked.
<table>
<tr><td>Do Not Change visisiblity</td></tr>
<div id="changerow">
<tr><td>Change this row</td></tr>
<tr><td>Change this row</td></tr>
</div>
</table>
the work around I've implemented is to place a class tag in each of
the tr tag and then doing a show and hide on rows with that class.
I was only hoping for a more elegant way. Anyway have any ideas?
