The table should have a ingredients storage box or cabinet to store all your ingredients. Then, when you go to craft, all ingredients in the storage box are available to use. This way, you don't have to keep storing and retrieving, storing and retrieving, every time you want to make some potions.
Without this seemingly simple addition to the table, you either have to pull out every ingredient from your nearby storage chest, craft, and store everything back; or go through your storage picking out the materials you want, which can be time consuming and tedious when you have a list of 100 ingredients stored.
I asked for this back in Oblivion, too. Seems like such an easy thing to implement, I am surprised it wasn't included in Skyrim.
