upstream: egui table with header in bottom to top layout

[fokoid]

The REPL history table was breaking when I added headers to tables. But the other tables were fine. The difference? The REPL history table sits within a bottom to top layout.

Need to figure out exactly what's going wrong and file an upstream bug report if appropriate. My guess is that when the header is allocated in bottom to top layout it consumes the whole space since we start at the bottom and the top is hard coded as the top of the current view.
