I did something just like this in 2001; man, was it a pain to code! It was on 4.6, and I don't remember if Treat View Contents as HTML didn't exist, or if I just didn't know about it, but I couldn't figure out how to code a column that would display a select box, so I ended up creating the "view" via an agent URL that looped through a view and spit out HTML to create the tables. The code I used for the submit button was actually fairly similar to what you wrote, but I'm betting it took me a whole lot longer to come up with...
Then, of course, the users weren't happy with a single button that would save all their changes; they wanted to have the option of clicking that one button, but also wanted to be able to selectively save changes, so I had to code a submit button on each row as well.
