The table might be generally true, but not necessarily true for all lenses. For the old manual lenses (pre-AI) and the D50, the table said "No!". That meant "Definitely do not use, for it may damage the camera body."
I carefully tried my old Nikkor 50mm F1.4 on my D50 and it fit and worked just fine. Manual focus and manual exposure, of course. It's such a nice piece of glass I didn't want to get rid of it.
