Conflicting GitHub and Observable CSS

First of all, I find dataflow fantastic!

Using It I've noticed that rules from GitHub markdown CSS (being used for all cells) sometimes clashes with the ones from Observable. For example if you create a cell with Inputs.table(), the generated table will have neither the horizontal scroll bar nor the sticky header.

A possible solution to this problem could be to create a specific CSS for dataflow, eventually using GitHub one as a starting point.
