Current behavior

ScrollbarHelper service is unreachable from outside. I can't import ScrollbarHelper, and it makes impossible to extend DatatableComponent because It's not possible to write constructor

class MyComponenet extends DatatableComponent {
    constructor(scrollbarHelper: ScrollbarHelper, element: ElementRef, differs: KeyValueDiffers) {
        super(scrollbarHelper, element, differs)
        ...
    }
    ...
}

Expected behavior

It should be allowed to import ScrollbarHelper. Besides, why is ScrollbarHelper implemented as a service? Should it be 'injected'? There is no way to inject ScrollbarHelper from outside, because of the same reason that I can't import ScrollbarHelper. Reproduction of the problem

What is the motivation / use case for changing the behavior?

I want to extend DatatableComponent.

Can you make a PR just to export this?
