Well its an extra attribute causing no harm right? Its a unque identifier added to the table.

 useMountEffect(() => {
        if (elementRef.current) {
            attributeSelector.current = UniqueComponentId();
            elementRef.current.setAttribute(attributeSelector.current, '');
        }

That way later with CSS selectors that can select this table if many tables like..

 let selector = `[data-pc-name="datatable"][${attributeSelector.current}] > [data-pc-section="wrapper"]
