Table has a dish, gold (7)
I believe the answer is:
plateau
'table' is the definition.
(I've seen this before)
'a dish gold' is the wordplay.
'a dish' becomes 'plate' (plate is a kind of dish).
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'plate'+'au'='PLATEAU'
'has' is the link.
(Other definitions for plateau that I've seen before include "Flat highland" , "Table" , "Area of level high ground" , "Stop progressing" , "Flat raised land" .)
