Enchanter Villager

Of course the Enchanter will use an Enchanting Table, but the level of the Enchanting Table will affect what the Enchanter will sells you. You could give them your tools and some emeralds to enchant, instead of XP and lapis, or maybe you could give them books and they give semi random enchants back. Each item will only show some enchants, but the rest are hidden. The enchants you can see are guaranteed, but the level of the enchants, as well as the chances of getting more are based on the Enchanting Tables own magical capacity.
