[ solved ] RStudio IDE Viewer is not rendering the styled HTML output from ztable package

:smile: Sometimes half the problem is figuring out the right search term! The auto-rendering that the RStudio IDE does is magically helpful when all goes well, but can sure be confusing when you run into trouble.

If you do find an answer on SO, you should link to it here for everyone's benefit! And if you wind up posting a new question on SO, definitely say so here (to abide by this community's cross-site posting policy).

Good luck!
