Adding A Total Row at the End of a JTable

Hi All,

I wish to add a total row at the end of my data in a JTable. However I want the total row to always remain visible throughout scrolling and when data is sorted.

I came across suggestions about using two tables but wouldn't the second table aka the total row be below the JScrollPane?

Another suggestion was interesting > link

Jeff Albertson suggested adding the row to the south region of the JScrollPane. How would that be implemented?

Any other suggestions on methods to implement the total row at the foot of the JScrollPane?

this might be one way, but you'll probably need to tweak the column widths

import javax.swing.*;
import java.awt.*;
import javax.swing.table.*;

class Testing
{
  public void buildGUI()
  {
    String colNames[] = {"Col 0", "Col 1","Col 2", "Col 3"};
    DefaultTableModel dtm = new DefaultTableModel(null,colNames);
    dtm.setRowCount(100);
    JTable table = new JTable(dtm);
    for(int x = 0, r = table.getRowCount(); x < r; x++) table.setValueAt(""+x,x,0);
    JTable footer = new JTable(1,4);
    JPanel holdingPanel = new JPanel(new BorderLayout());
    JScrollPane sp = new JScrollPane(table);
    sp.setPreferredSize(new Dimension(300,200));
    holdingPanel.add(sp,BorderLayout.CENTER);
    holdingPanel.add(footer,BorderLayout.SOUTH);
    JFrame f = new JFrame();
    f.getContentPane().add(holdingPanel,BorderLayout.CENTER);
    f.getContentPane().add(sp.getVerticalScrollBar(),BorderLayout.EAST);
    f.pack();
    f.setLocationRelativeTo(null);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setVisible(true);
  }
  public static void main(String[] args)
  {
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
      }
    });
  }
}
