Think that any time I combine noun + noun I have to add the suffix to the final noun. For example, patlıcan (eggplant) is a noun, and salata is a noun (salad). If I want eggplant salad, it's patlıcan salatası. Or consider the different types of börek: gül böreği (rose borek), sigara böreği (cigar borek), su böreği (water borek), etc.
wood table doesn't fit there anyway as "wood" (or wooden) is used there as an adjective.
this is valid only if you have two nouns ; and many languages have similar constructions http://en.wikipedia.org/wiki/Compound_(linguistics)
