I have a table where I show/hide a full column by jQuery via a CSS class that doesn\'t exist:

    There are no ill effects to use classes which don't have styles.  Indeed, that's part of the usefulness of CSS is that it's de-coupled from the markup and can style or not style elements/classes/etc. as needed.
    


    Don't think of them as "CSS classes."  Think of them as "classes" which CSS happens to also use if it needs to.
