Yeah, the closest I can think of for tablature for keyboards would be the piano roll in MIDI editors and sequencers:
People do use these for visualization, and it’s a fantastic way to edit MIDI, but you are not likely to print it and try and play from it
You see them used in animated ways to demonstrate songs all the time though, like this:

Bottom line is that for keyboards, you want standard notation.
