Type of table Director General takes home twice (6)
I believe the answer is:
dining
'type of table' is the definition.
'director general takes home twice' is the wordplay.
'home twice' can mean two replacements for 'home'.
'director general' becomes 'DG' (abbreviation in organisations eg the BBC).
'takes' indicates putting letters inside.
'home' becomes 'in' ('he's home' can mean 'he's in').
'home' becomes 'in' ('he's home' can mean 'he's in').
'in'+'in'='inin'
'dg' going around 'inin' is 'DINING'.
(Other definitions for dining that I've seen before include "This room is for eating in" , "at lunch?" , "Eating Dinner" , "Eating at table" , "Making a meal of" .)
