سلام
من نمیدونم مشکل شما کجاست!
مثالی که آقای فدوی زدن و اون لینک ها همشون کارتونو را میندازه، ولی به هر حال یه چیزی نوشتم که راحت باشه :
import javax.swing.*;
import javax.swing.table.DefaultTableModel;
import java.awt.*;
/**
* @author avb
*/
public class TableButtonExample extends JFrame {
public TableButtonExample() {
super("TableButton Example");
DefaultTableModel model = new DefaultTableModel();
model.addColumn("Column 1");
model.addColumn("Column 2");
model.addRow(new Object[]{"Row 1", "Delete"});
model.addRow(new Object[]{"Row 2", "Delete"});
JTable table = new JTable(model);
TableButton deleteButton = new TableButton(table, 1);
deleteButton.addActionListener((event, row, column) -> System.out.println("delete : row = " + row + ", column = " + column));
JScrollPane scroll = new JScrollPane(table);
add(scroll);
setDefaultCloseOperation(WindowConstants.EXIT_ON_C LOSE);
setSize(400, 400);
setLocationRelativeTo(null);
pack();
}
public static void main(String[] args) throws Exception {
UIManager.setLookAndFeel(UIManager.getSystemLookAn dFeelClassName());
EventQueue.invokeLater(() -> new TableButtonExample().setVisible(true));
}
}
کلاس TableButton :
import javax.swing.*;
import javax.swing.table.TableCellRenderer;
import javax.swing.table.TableColumnModel;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.util.ArrayList;

TableButtonListener :

}
شما به این 2 تا کلاس کاری نداشته باشید و فقط به برنامتون اضافش کنید (فکر کنید توی خود swing همچین کلاسایی هست).
تمام کاری که شما باید انجام بدید همین چند خطه :
TableButton deleteButton = new TableButton(table, 1);
deleteButton.addActionListener(new TableButtonListener() {
@Override
public void actionPerformed(ActionEvent event, int row, int column) {
//handle event
}
});
