operating table

I'm a little stuck... Click here to teach me more about this clue!

'realm of surgery' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'working with list in' is the wordplay.
'working' becomes 'operating' ('operate' can be a synonym of 'work').
'with' is a charade indicator (letters next to each other).
'list in' becomes 'table' (list can mean a table or chart. I am not sure about the 'in' bit.).
'operating'+'table'='OPERATING-TABLE'

Can you help me to learn more?

(Other definitions for operating table that I've seen before include "Hospital theatre equipment" , "where one's out for incisive remedial action" .)
