Grid Like Project Web Access??

I'm working on an application that needs a pretty complicated grid. What I need is either a grid that can split into a left-pane/right-pane orientation with separate horizontal scroll bars for each pane (while incorporating a single vertical scroll bar controlling both panes simultaneously), AND a column that provides a check-box for row selection, AND the ability to expand/collapse "sub-rows" according to a hierarchy of three levels (resource, project, task). By the way, if we could somehow automatically sum values from lower levels to their summary rows, that would be super.

Can your grid control support such a complex design?
