Hi, guys. I appreciate your feedback on DataFrame.
Datalore has recently reused its visualization control (that was used for Pandas) for Kotlin DataFrame. It provides lazy loading and charts, but doesn’t support hierarchical DataFrames and cell rendering customization (e.g. ability to display any HTML or media in a cell), that native DataFrame control has. We are currently discussing unification of these two controls.
There is no way to override CSS yet, but I’ll add ability to disable it
