Seems to still be an issue

Is this relevant @gmoehler ?

[gmoehler]

@sstrubberg sorry for the late response. in fact we have been using a sticky table unchanged since that time in the product, and had to add a number of css styles to make it working. Unfortunatelly, the current carbon 10 react storybook no longer has the option to set parameters via knobs, so it is hard to easily prove its current state. So I assume it is still relevant.

This is still an issue.

Yeah, here's an example of it in the current storybook

@gmoehler could you share some of the overrides you've made to get this working? Would love to get those fixes upstream here if possible!
