I am sorry your father has done what he has done to you. It could be that someone in the family has been talking to him, and he has gotten incorrect information. The thing about weddings, funerals and such, you can't undo a mistake as far as someone not going to someone not inviting a person for their own reasons.
I know of a situation where a man refused to go to his daughter's wedding, and after the wedding she was moving about 800 miles away. The thing I was worried about was if something had happened on that trip, and god forbid, she has passed away, I would wonder if he would have had the same thought of I showed her, I didn't approve of her marriage or moving!
Sometimes we allow hate/anger to alter our clear thinking, and we do stupid things. Maybe you should attempt to meet with your father, and the two of you get the other's side of why what happened, and attempt a repair of the relationship. You don't know what someone from your family may have told him, for their own agenda. If he is not willing, well there is not much you can do other than have peace of mind, knowing you tried.
I hope this helped, good luck, and I hope you can make amends
