There may be a way to do what you want in OG. In fact, I'm sure there is. But a quick, easy, easily adaptable way? I don't think so. (But I'm all ears if someone has a great idea out there.)

That said, it seems all of your needs can be easily met using OmniOutliner Pro. I use it for similar needs all the time. You've got checkboxes, easy to update for your needs, and all the rest. Granted, it looks more like an indented outline than a table, but it's a great quick way to accomplish what you want. Unless there's some strong reason you need the look of a table per se, rather than an indented outline, OO would seem to be the way to go.
