Flash On Update

Hey --

I'm wondering if there is a way to temporarily highlight a cell when its value updates? For example, if a number in a cell goes up, it would highlight green, if the number goes down, it would highlight red. The highlight would expire after a small interval (perhaps 1 second).

Any ideas on how to achieve this?

The issue names no files, tests, or entry points. Start by locating the table's cell rendering and update handling, then clarify the desired change, including how value direction and the temporary highlight should be represented and tested.
