Big table with both height and angle adjustable?
Look for a "drafting table". I happen to like the vintage ones, but there are more functional varieties with shelves, drawers etc. as well. 



Just a suggestion to help the planet: LOTs of people have been giving these things away for free or dirt cheap because companies don't do mechanical drafting any more and they take up a lot of space, so check out your favorite on-line resources (like Craigslist, Nextdoor etc.) before shelling out a lot of money.
