Make a cell or row visible programmatically.

	static void setCellVisible( JTable table, int row, int col )
	{
		Container p = table.getParent();
		if (p instanceof JViewport) {
			Container gp = p.getParent();
			if (gp instanceof JScrollPane) {
				JScrollPane scrollPane = (JScrollPane)gp;
				// Make sure the table is the main viewport
				JViewport viewport = scrollPane.getViewport();
				if (viewport == null || viewport.getView() != table) {
					return;
				}
				
				Rectangle cellrect = table.getCellRect( row, col, true );
				Rectangle viewrect = viewport.getViewRect();
				if( viewrect.contains( cellrect ) )
					return;
				Rectangle union = viewrect.union( cellrect );
				int x = (int)(union.getX() + union.getWidth() - viewrect.getWidth());
				int y = (int)(union.getY() + union.getHeight() - viewrect.getHeight());
				viewport.setViewPosition( new Point( x, y ) );
			}
		}
		
	}
