Extended Syntax For Markdown

[ng-chicago]

I need to add a sup tag inside a table cell (with other items in the cell)
With the Extended Syntax, I would do this in the markdown: ^↑^
But that seems to not work in eleventy

Is there a way to make it work?

Never mind user error.
sup tag in the cell works

(In case somebody else runs into this discussion in the future)

I'm using https://www.npmjs.com/package/markdown-it-sup with an amended Markdown-it.
