修饰符和类	方法	描述
static Component	SwingUtilities.getUnwrappedView(JViewport viewport)	Returns the first JViewport's descendant which is not an instance of JLayer.
void	JScrollPane.setColumnHeader(JViewport columnHeader)	Removes the old columnHeader, if it exists; if the new columnHeader isn't null, syncs the x coordinate of its viewPosition with the viewport (if there is one) and then adds it to the scroll pane.
void	JScrollPane.setRowHeader(JViewport rowHeader)	Removes the old rowHeader, if it exists; if the new rowHeader isn't null, syncs the y coordinate of its viewPosition with the viewport (if there is one) and then adds it to the scroll pane.
void	JScrollPane.setViewport(JViewport viewport)	Removes the old viewport (if there is one); forces the viewPosition of the new viewport to be in the +x,+y quadrant; syncs up the row and column headers (if there are any) with the new viewport; and finally syncs the scrollbars and headers with the new viewport.
