there is no 'set in stone' look... as long as its neat, precise and informative and has all the necessary info on, you can keep it simple.
the basics are still the same -
name, address, phone, email.
basic title header of your job name/s
start with most recent role and work backwards,
date, job title and company (Or company then job title is fine) brief outline of job and your role
then education and achievements.
referees available on request.
you can add a 'mission statement' at the top, and section on personal interests at the bottom if you want but its not essential.
i have very little formatting in mine - no indents or columns or boxes etc, just nicely spaced out and use bold and underline for emphasis - i have to update it very often you see so its easier to manage without all sorts of formatting etc
