Some of my apps are now fully invested in tidy data principles and make use of list columns in data frames to organize objects. I'd like to display some of these within my app and.some of my hacks include using DT and making a list column of character vectors just big strings delimited by commas. But that got ugly pretty fast! I use the listviewer widget by Kent Russell quite a bit in my dev work but the visuals don't mesh well with the overall app looks. Anyone have recommendations on other widgets or techniques to use in these situations?
