In Minecraft 1.9, End Cities spawn in the End. These End Cities contain Chests with various items, some of them enchanted. On the wiki I found out that the items may be enchanted to a random level from 20 to 39. By that they mean the level you enchant on in an Enchantment table (not Sharpness 30).
Can I get/give myself an Enchant table with a higher maximum enchantment level? If yes, how? I would really want it for my super-experimantal "survival" world.
