Row version of obj.setFixedLeft()?

I'd like to be able to fix several header rows in the same way that obj.setFixedLeft() fixes columns.

Ideally, I'd be able to scroll and sort without the fixed rows moving.

obj.setHeaderCount() doesn't work for this because (I think) it adds header labels rather than fixing existing rows in place.

If I could load multiple csv rows as header rows, that would address this problem, but I haven't found a way to do that.

Thanks!

No, this is not possible. The only option is to use extended grid with multiple header rows, but in this case the header cells content must be set separately from the scrolling cells ('normal' rows).
