Function h_virtual_list 

pub fn h_virtual_list<R, V>(
    view: Entity<V>,
    id: impl Into<ElementId>,
    item_sizes: Rc<Vec<Size<Pixels>>>,
    f: impl 'static + Fn(&mut V, Range<usize>, &mut Window, &mut Context<'_, V>) -> Vec<R>,
) -> VirtualList
where
    R: IntoElement,
    V: Render,

Create a VirtualList in horizontal direction.

The item_sizes is the size of each column, only the width is used, height is ignored and VirtualList will measure the first item height.
