How do you set new items within a JComboBox that is within a JTable

Question

I have searched and searched for the answer to this and do not thing there is one. I have a JTable that has 5 columns. 2 of the columns use DefaultCellRenderers where a JComboBox is used. One of the columns has a value of different football positions. The other has a value of the different players. When a user enters a particular position such as Kickers I want all the Kickers to be showin within the Players JComboBox within the table.
The problem is that I ONLY want the cell to be modified within that row and column that the position was changed. I have found ways to modify the component but it modifies it for the whole Column. I only want it to be modified for the player cell within the row that the Position was modified. Bottom line is that I just want to modify the JComboBox's components.
If anyone has had this challenge before please advise.

I'm not sure I fully understood what you wanted. Does the following little program help you?import javax.swing.*;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableColumnModel;
import java.awt.*;

public class FootballTable extends JPanel {
     private static final String[] COLUMN_NAMES = {"Position", "Name"};
     private static final String[] POSITIONS = {"goal", "arriere", "milieu", "avant"};
     private static final String[] GOALS = {"goal1", "goal2", "goal3"};
     private static final String[] ARRIERES = {"arriere1", "arriere2", "arriere3"};
     private static final String[] MILIEUX = {"milieu1", "milieu2", "milieu3"};
     private static final String[] AVANTS = {"avant1", "avant2", "avant3"};
     public FootballTable() {
          super(new BorderLayout());
          DefaultTableModel model = new DefaultTableModel(COLUMN_NAMES, 10);
          final JTable table = new JTable(model);
          TableColumnModel columnModel = table.getColumnModel();
          columnModel.getColumn(0).setCellEditor(new DefaultCellEditor(new JComboBox(POSITIONS)));
          columnModel.getColumn(1).setCellEditor(new DefaultCellEditor(new JComboBox()) {
               public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
                    JComboBox nameComboBox = (JComboBox)super.getTableCellEditorComponent(table, value, isSelected, row, column);
                    Object position = table.getValueAt(row, 0);
                    if (position == null) {
                         nameComboBox.setModel(new DefaultComboBoxModel());
                    } else if (position.equals("goal")) {
                         nameComboBox.setModel(new DefaultComboBoxModel(GOALS));
                    } else if (position.equals("arriere")) {
                         nameComboBox.setModel(new DefaultComboBoxModel(ARRIERES));
                    } else if (position.equals("milieu")) {
                         nameComboBox.setModel(new DefaultComboBoxModel(MILIEUX));
                    } else if (position.equals("avant")) {
                         nameComboBox.setModel(new DefaultComboBoxModel(AVANTS));
                    } else {
                         nameComboBox.setModel(new DefaultComboBoxModel());
                    return nameComboBox;
          add(new JScrollPane(table), BorderLayout.CENTER);
     public static void main(String[] args) {
          try {
               UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
          } catch (Exception e) {
               e.printStackTrace();
          final JFrame frame = new JFrame(FootballTable.class.getName());
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.setContentPane(new FootballTable());
          SwingUtilities.invokeLater(new Runnable() {
               public void run() {
                    frame.setSize(400, 300);
                    frame.show();
}Sorry for the French words, I have no idea how they are called in english (and too lazy to search).
There is another solution. You also can override the table's prepareEditor method and add the relevant code before returning the Component.
