Straight on table (5-5)

I believe the answer is:

above-board

'straight' is the definition.
(thesaurus)

'on table' is the wordplay.
'on' becomes 'above' (I've seen this before).
'table' becomes 'board' (board is a kind of table**).
'above'+'board'='ABOVE-BOARD'

(Other definitions for above-board that I've seen before include "Honest" , "Straight" .)

I've seen this clue in The Independent.
