I'm not quite sure I understand what I am looking at. Is it some sort of metal hardware that is part of the table? (It looks like a button sitting on top of the table to me.) 

[mckha489]

is it a knob on a drawer in the table?

googling I found this sentence

"Some old dresser pulls are simply metal or wood knobs attached to the drawer. This is common in sewing cabinets or spool cabinets, but you'll also see basic knobs on antique dressers, side tables, and other pieces. It is difficult to use knobs to date a piece of furniture, since this simple design has been popular for centuries."

There is a similar foot on a table near me at the moment and that is from the 1930s.

Your 'iron'mongery may well be something like bronze if the greenish tinge is there in real life.
