PHPMyAdmin field Tables

PHPMyAdmin field Tables

I am wanting build a database for a Chat site register page, the site I
have seen all have ID as the first listed in the field table. Does it
really matter the order the field names are listed in? as the Register
page that I have starts with: Email User Password Gender then 4 questions
that require a check to complete before clicking register, can you also
tell me if the check questions and register need to be in the field table
as well.
I also want to have on the register page Country and then from a drop down
City..
I hope I have explained this ok...
