Table Cell Changes

Hello!

I’d like to change font colors, font sizes, background color, and border for individual cells in my pricing table. I can’t seem to find the right selectors in CSS (at least I think that’s what my issue is!). I’d love to see a code template so I can implement myself and in the future. For this example, lets say this is a 2 column x 5 row table. The first row is a header, the middle 3 rows are body, the last low is pricing row.

Thank you,
Michael
