It's not super easy either. I ran into this also (https://doc.sscaffold-css.com/ysk/tables/) and the root cause is that the <table> element is not considered to be either a block-level or an inline element. It's special, and because it's special, some browsers support setting max-width on it and some don't. So tables need a container element or some other kind of special handling. It's an easy bug to overlook because the cause is so unexpected.
