[jQuery] Re: before() and after() does not work on unclosed tags?

[jquertil]

after a litle thinking i realized this could be done easier by doing
the opposite, using wrapinner()

<table><tr class="head"><td>generic header stuff</td></tr>
<tr class="main"><td id="wrapit"></td></tr></table>

$('#wrapit').wrapinner('<div id="somediv">...</div>');
