You will just have to over-ride the bootstrap styles on your table. Mind you Bootstrap doesn't actually apply any heavy styles by default to tables unless you are using some of their pre-defined classes. I didn't run into any problems with tables when I used them in bootstrap.
bootstrap 2.2.3 is better for new user but bootstrap 3.0 is for upper user.
Bootstrap 3 is just the new version with the mobile first approach and is no harder/simpler than the previous version It's just different.
