Unrelated to that issue, the right hand side TOC does not display completely. I am using firefox on windows with a default zoom of 120%. The TOC ends up going below the screen and hiding the last few entries. It also floats above the footer and hides the text there.

If I may suggest, use `position: sticky` instead of `position: fixed` or some equivalent to whatever trick you used.

I'm trying to but the entire page scrolls horizontally instead of just the code block.

It might be because of the larger tables. Thanks for letting me know--I'll take a look at it soon.
