TableView Header Issue

[gabereiser]

The TableView Demo's Header isn't flush to the scrollbar in Chrome. The TableView should scale horizontally to the width of the window under Chrome to that there isn't a gap between the top of the TableView and the scrollbar starting region. Currently in Chrome there is a gap due to blocking of the TableView div not being flush with the entire width contents. See: http://demo.sproutcore.com/table_view/ in Chrome.
