grid v1.0 - is there a way to 'unfix' the header?

Is there a way to tell the header not to be 'fixed'.

I need to customize the grid a little for my application, and I want to retain the header so that the user can change the column sizes.

I want to restyle the header so that it looks like one of the rows of the table, and so that it can be used as such. I want to retain the column resizing functionality. I want to block the user from using the sorting functionality.

I've solved the styling and sorting. But when a user scrolls down, the header stays fixed to the top of the table.

I need a way to make the header scroll with the rest of the rows. Can this be done easily?

Not as far as I know.
