It has legs or maybe columns (5)
I believe the answer is:
table
'it has legs' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for table that I've seen before include "Food stand or numbers array" , "Dummy hand (bridge)" , "Board; data list" , "Food; flat gem surface" , "Item of furniture; figures presented in columns" .)
