Java Swing - 如何保持JTable选择

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;

public class Main {

  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JTable t = new JTable(10, 1);
    frame.add(new JScrollPane(t));

    t.getSelectionModel().clearSelection();
    t.getSelectionModel().addSelectionInterval(5, 6);
    t.getSelectionModel().addSelectionInterval(8, 8);
    frame.pack();
    frame.setVisible(true);
  }

}
