The question is are you trying to build a desktop class application or not. If not jquery/backbone is the obvious solution.

If a tablview is particularly interesting to you Cappuccino (http://cappuccino.org) has simply the best tableview out there.

This is what it was like several months ago, and it has only gotten better. http://timetableapp.com/TestingEnviro/imdbdemo/

It's fully customizable too, supporting any kind view you want to put in it, and will remain very snappy.

http://githubissues.heroku.com for example shows of some of this flexibility and performance in a real world app.
