Pandas dataframe columns rendered using nbsphinx don't flex with pydata-sphinx-theme 0.10.1 (scrunched output)

[taylorm0192]

Using pydata-sphinx-theme v.0.9.0 and nbsphinx v.0.8.9, pandas dataframes are rendered with the correct margin/padding between cells. Rebuilding with v0.10.1 (same nbsphinx version), the cells are scrunched together (individual columns don't flex to accommodate data longer than the default width).

If repro is not as simple as rebuilding a toy notebook w/ nbsphinx using pydata-sphinx-theme 0.10.1, then please let me know and I will try to create an example.
