Swing/AWT/SWT :: Sizing JScrollPane Width To Its Contained JTable

Returning true from getScrollableTracksViewportWidth() makes the table (or other Scrollable) size its width to match the viewport. I need the opposite: for the viewport to expand its width to accommodate the table (of course, limited by the constraints imposed by the scroll pane's container's layout manager) without reducing column widths i.e. setAutoResizeMode(AUTO_RESIZE_OFF).

I have achieved this by overriding

getPreferredScrollableViewportSize(): JTable table = new JTable() {
@Override
public Dimension getPreferredScrollableViewportSize() {
return new Dimension(super.getPreferredSize().width,
super.getPreferredScrollableViewportSize().height);
}
};

Now when the scroll pane is added at BorderLayout.CENTER and the frame is pack()ed, all columns of the table are displayed, without need for a horizontal scrollbar.
