I tried sproutcore for a project about 2 years ago and couldn't make the table widget work with page up, down etc.
Instead I finalized on qooxdoo - http://qooxdoo.org/ and was impressed with it and the mailing list was and is responsive and the developers from 1&1 quick to fix any bugs I found :)
And I finally had the table widget I always wanted with keyboard shortcuts for all the things I wanted.
Of course, it could be me not knowing enough to make sproutcore's table widget work like I wanted, since I was only a beginner in JS back then.
Edit: The demo at http://demo.sproutcore.com/table_view/ for the table still doesn't work with page up or page down. Maybe the feature is there, but not enabled for this demo.
