jupyter nbconvert to html: datatable and qgrid not shown in html output

Question

Datatables and SlickGrid tables are not shown in the final html file after nbconvert'ing a previously executed ipynb file.

The python libraries I am using are:

• qgrid https://github.com/quantopian/qgrid
• jupyter_datatables https://pypi.org/project/jupyter-datatables/

What I'm attempting

I am rendering dataframes as html tables in my jupyter notebook. When executing the notebook manually all works well (i.e. the tables are shown).

For instance, a cell using qgrid looks something like this

qgrid_widget = qgrid.show_grid(my_dataframe)
qgrid_widget 

I run the notebook, tables are shown, all works well...

Where things break...

But when I convert the notebook to html afterwards, running

jupyter nbconvert --to html my_notebook.ipynb --no-input

The tables are not shown (while all other output is). This happens with both qgrid and jupyter_datatables. I assume that has something to do with properly loading the underlying javascript libraries.

How do I need to run nbconvert to render these tables correctly?

Thanks
