[Powertop] powertop 2.1 isn't measuring task power properly on my Thinkpad T530

Howdy,

I just downloaded and built 2.1, and a couple of things aren't right:
1) header columns aren't aligned with the data
2) power estimate shown in the kW range :)

See screenshot of 2.1 vs 1.98:

Is there other info I can provide?

Thanks,
Marc
