microsoft word – Table default font size

I have multiple tables in my document. By default they use “Normal” style for any texts inside. However, while I keep my paragraph font size 14, I want to use font size 12 inside tables by default (and thus apply it to all current and future tables in this document and change them on the go if I find the need to so). How can I make it happen?

Tweaking each and every table separately is not a good option. So I am looking for a way similar to editing default styles.
