JTable Grid Lines

Question

How can I make the Grid Lines (Vertical and Horizontal) of the JTable extend to the bottom even without data? Any suggestion is highly appreciated. Thank you.

Well, you can add some custom painting yourself. Here is a simple example that might get you started:
import java.awt.*;
import javax.swing.*;
public class TableLines extends JFrame
     JTable table;
     public TableLines()
          table = new JTable(10, 5)
               public void paintComponent(Graphics g)
                    super.paintComponent(g);
                    g.setColor( Color.RED );
                    int y = getRowHeight(0) - 1;
                    g.drawLine(0, y, getSize().width, y);
          table.setPreferredScrollableViewportSize(table.getPreferredSize());
          JScrollPane scrollPane = new JScrollPane( table );
          getContentPane().add( scrollPane );
     public static void main(String[] args)
          TableLines frame = new TableLines();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.pack();
          frame.setLocationRelativeTo( null );
          frame.setVisible(true);
}
