Page finds table extender (4)
I believe the answer is:
leaf
I believe this clue is a double definition.
'page' is the first definition.
(leaf can mean a page)
'table extender' is the second definition.
(I've seen this in another clue)
'finds' acts as a link.
(Other definitions for leaf that I've seen before include "Bit of foliage" , "Turn over a new one to reform" , "Organ of photosynthesis in plants" , "Sheet of written material" , "Thin sheet of metal" .)
