I get the same result as markspace. If I use an unbound key, I get your
result. The problem is invoking fireTableRowsInserted() for a second
time in addRow(). I'm not sure why you override addRow(), which already
provides the required notification.

I'm not sure of your goal, but here's a simplified example of adding a
row to a DefaultTableModel via mouse or keyboard:

import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;

public class NumericColumnTester extends JFrame {

    private DefaultTableModel model_001 = new DefaultTableModel();
    private int i;

    public NumericColumnTester() {
        String[] header = {"Text", "Num 1", "Num 2"};
        model_001.setColumnIdentifiers(header);
        model_001.addRow(nextRow());
        model_001.addRow(nextRow());
        JTable table = new JTable(model_001);
        table.setRowSelectionAllowed(false);
        JScrollPane scrollPane = new JScrollPane(table);
        this.add(scrollPane);

        this.add(new JButton("Add Row") {
            {
                addActionListener(new ActionListener() {
                    @Override
                    public void actionPerformed(ActionEvent e) {
                        model_001.addRow(nextRow());
                    }
                });
            }
        }, BorderLayout.SOUTH);

        table.addKeyListener(new KeyAdapter() {
            @Override
            public void keyPressed(KeyEvent e) {
                int key = e.getKeyCode();
                System.out.println(" Key: " + KeyEvent.getKeyText(key));
                if (key == KeyEvent.VK_F16) {
                    model_001.addRow(nextRow());
                }
            }
        });
    }

    private Object[] nextRow() {
        return new Object[] {
            Character.valueOf((char)('a' + i++)),
            Integer.valueOf(i),
            String.valueOf(i)
        };
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                JFrame frame = new NumericColumnTester();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
            }
        });
    }
}
