If the table just says “Loading…”, then maybe
You loaded a notebook that is not trusted (run “Trust Notebook” in View / Activate Command Palette)
You forgot to run
init_notebook_mode, or you deleted that cell or its output
Or you ran
init_notebook_mode(connected=True)but you are not connected to the internet?
Please note that if you change the value of the
connected argument in
init_notebook_mode cell, you will need to re-execute all the cells
that display interactive tables.
If the above does not help, please check out the ChangeLog
