Cell table output displays unreadable

[rcpeene]

Describe the bug

context I am using Thebe in Jupyterbook to display a pandas dataframe as cell output. When the static notebook is displayed, the tables look fine. But after running it with Thebe's live code button, the outputted table looks very messy/ Previously, the table would display in a scrollable format (with output_scroll in the cell's tags). As of my latest deployment, though, this does not happen.

expectation I expected a readable table output to appear

bug But instead, the dataframe table output shows without properly alignment in an unreadable form. Like the following.

problem This significantly reduces the usability of outputting pandas tables.

Reproduce the bug

1. Download this jupyter notebook file https://github.com/AllenInstitute/openscope_databook/blob/main/docs/first-order/optotagging.ipynb
2. In the repository, run the latest jupyterbook build with jupyter-book build ./
3. Open the file and scroll down to view the tables. (running the file is not necessary)

List your environment

I am using the latest version of Jupyter Book available on Pip; 0.15.0

Confirmed that this is not an issue with jupyter book 0.13.2 but is for version 0.14.0

Revised the 'to reproduce' steps above.

It appears not to happen only with pandas tables but any form of output table.
