Seems pretty much impossible to not have an accessibility mode yet have features such as fixed columns/rows. It would be very difficult to have a clean DOM structure while supporting that layout. If it is possible I'd be very interested in how that is done.

It can be done if you are using a Canvas to provide the rendering. The canvas can then be provided with a subdom that does not render but is visible/interactive to screen readers which matches exactly what the screen reader requires. Canvas's actually have the advantage here if they put the effort into being accessible.

You could do the same trick by hiding the visible DOM from the screen reader and creating an invisible DOM explicitly for the screen reader. If your DOM structure is wrong for the screen reader I would suggest doing this.
