I don't know all your requirements, but SlickGrid is worth another look if
you want to be able to present and filter hundreds of thousands of rows,
because as far as I know it's the only plugin that can currently do that:
On the downside, it's feature-heavy, as you say, has its own idea of what a
data model should be, and the documentation is minimal.
