Resize google table chart row height

I have a google visualization dashboard with a table chart (as in https://developers.google.com/chart/interactive/docs/gallery/table) displaying some data shown below. Ive managed to change the font size of the table using CSS Class Names but the row height is still the default size - which Id like to change and make smaller.

What Ive used for the font - CSS:

    .small-font {
    font-size: 10px;
    }

javascript:

    var cssClassNames = {
    tableCell: 'small-font'
    };

Is there a way to do this using CSS or another method?
