ItemEvent の後に JTable 内の JComboBox の行番号を取得するにはどうすればよいですか?

public void itemStateChanged(ItemEvent e) {
    // Get the table cell editor
    TableCellEditor editor = table.getCellEditor();
    // Get the row of the cell being edited
    int row = table.convertRowIndexToModel(editor.getTableCellEditorComponent(table, ...));
    //...
}

import javax.swing.table.DefaultTableModel;

//...

// Override getValueAt() to keep columns synchronized
@Override
public Object getValueAt(int row, int col) {
    if (col == DEPENDENT_COL) {
        return "C2:" + this.getValueAt(row, ITEM_COL);
    } else {
        return super.getValueAt(row, col);
    }
}

//...

// Attach a new ItemListener
combo.addItemListener(new ItemListener() {

    @Override
    public void itemStateChanged(ItemEvent e) {
        if (e.getStateChange() == ItemEvent.SELECTED) {
            // Get the table cell editor
            TableCellEditor editor = table.getCellEditor();
            // Get the row and update the other column
            int row = table.convertRowIndexToModel(editor.getTableCellEditorComponent(table, ...));
            model.setValueAt("C2:" + e.getItem(), row, DEPENDENT_COL);
        }
    }
});
