This is the same as my experience, and it makes sense because turning on prettification does not take care of the alignment. The problem I have is exactly related to what you described below, i.e. the table alignment after a realignment.

I have a different experience for this.
In my case, after a realignment (by pressing TAB or C-c C-c), I got 

| a  | b | c |
|----+---+---|
| α |   |   |

instead of 

| a | b | c |
|---+---+---|
| α |   |   |

It looks like that a greek letter is considered to be a double-wide symbol but displayed as a single-wide one.

This is surprising as I can reproduce the issue with a clean init file.
Btw, I am using org-plus-contrib package (20160822) with emacs 25.1.50 on a mac (10.11.6).
