Change table, in a manner of speaking (5)
I believe the answer is:
alter
'change' is the definition.
(synonyms)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for alter that I've seen before include "convert" , "Bout of extravagant spending" , "Make changes to" , "Revise" , "Amend" .)
