jquery ui sortable table columns with fixed rows issues
<p>There is a jquery ui sortable widget <a href="http://dbrink.github.com/sorttable/examples.html" rel="nofollow">extension</a> which makes table columns sortable.
According to examples page it is possible to specify row as undruggable. </p>

<pre><code> $(function () {
    $('#ex7').sorttable({
        placeholder: 'placeholder',
        helperCells: ':not(.footerrow td)'
    }).disableSelection();
    });​
</code></pre>

<p>I want to set several colspanned rows such way. 
But there are several issues occur when i set fixed rows in the middle of the table.
First - fixed rows is not showed as dragged during drag&amp;drop, second - after several movements table becomes broken.</p>

<p>Is there any way to correct it?</p>

<p><strong>UPDATE:</strong></p>

<p>found workaround using absolute positioned div with width=table width, but actually i don't like it</p>
