How to use

As mentioned above Using the CSS vars from the table allow us to style our grid. Let's say that we want to change the grid to use a Dark Theme, by changing the following header background and text colors etc., we can do that like so in a file optionally called dark-theme.css.

import "./dark-theme.css";
