expand table

Hi everybody !
I noticed that when I expand a table in order to show another panel, then if I change a selector without clicking on the table to un-expand it beforehand, when I open the table again, cde stops working
I am not sure if it's a bug or if there is a way around that (maybe put some javascript in my selectors to un-expand the table automatically in pre-change or something)
If you have any idea, please let me know
Thanks !
