Can Somebody Answer this question
Also Can we have the property of colspan and row span and breakbefore in rich scrollable data table
It's not possible in SDT in 3.3.x and will not be supported for 4.x also. Ajax scrolling (which is core feature of that table) just can't support that (at least without too huge script workarounds). And we believe even if we will be able to add such support it will cause huge performance problems.
