Saving a Jupyter notebook as HTML does not save pandas dataframes

When we export a notebook at HTML outside of BeakerX, the dataframe tables are preserved. This makes sharing notebooks with people who do not have any coding experience very easy.

The interactive dataframes are not saved when we export to HTML.

The issue identifies Jupyter Notebook HTML export and interactive pandas dataframes, but names no files, tests, or entry points. Start by reproducing the export outside BeakerX with a notebook containing a dataframe, then compare the result with the preserved tables described in the issue. Done means the interactive dataframe content is present in the exported HTML.
