How to always show only the horizontal scrollbar on a ListGrid

Is there a way to always display the horizontal scrollbar, even if is not active, but the vertical scrollbar should be always hidden.

Setting setBodyOverflow(Overflow.SCROLL) will show always both of the scrollbars.

I tried adding a styleName and applying a custom css with both overflows:
overflow: scroll;
overflow-y: hidden;

but nothing happended.

I will appreciate any workaround also.

Thanks.
