The writers of phpMyAdmin obviously didn't realise that you didn't
need that information. In their ignorance they went and built it to
display all the relevant information about the fields, for all the
other people who need to know the details. Crazy huh!
I notice the same with MicroSoft Windows. There are things in here
that I find totally unnecessary. So I assume that no one else needs
those features either!
