Datatable span performance

Is there any way of increasing the performance when using spans? They don't seem to get virtualized like the rest of the grid cells.

    Do the spans significantly decrease performance in your datatable?

    Currently we do not have lazy rendering for spans. Most probably you can try adding spans dynamically when the view is scrolled down:

    grid.attachEvent("onAfterScroll", function(){
         //determine whether the row is visible and it requires a span
         this.addSpan( .. );
