Formatting Table Options within this Theme

Is there a way I can find out how to format my table the way I want in this theme? As you can see my page, the problem is only the first 6 columns of the table show.
I’d like to have a few more columns show, and change the format/coloring.

Is it possible that I can format this table here at my theme/page and also remove that extra white space at the top of the space?

I’ve gone into the Table Press > Plugin Options > Frontend Options > Custom CSS
and attempted to put some code there, but not sure if I am in the right place, or if this is the place I need to get the whole table looking exactly as I want.

Thanks,
