I installed grappelli and the sortable app from ff0000-django-sortable on github and everything works perfectly but one detail you can see in the picture in this link
The header of the table is displaced to the right. This only happens when the sorting is enabled. If I sort any other field (clicking on other column header) the header looks ok. I also realize the problem is on the javascript function "$(table).find('tbody').sortable()" in "django-admin-sortable.js"
I guess this is easy to fix but I can´t find where or how. Can anyone point me to the right direction?
