I want to add jButton inside column and then delete row using added jButton I've tried some stackoverflow questions and have following code but that doesn't deleting a row.

public class NewJFrame extends javax.swing.JFrame {



    JButton jb = new JButton();



    public NewJFrame() {

        initComponents();



        jTable.getColumn(" ").setCellRenderer(new TableCellRenderer() {

            @Override

            public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {

                jb.setText("Delete");

                return jb;

            }

        });



        jTable.getColumn(" ").setCellEditor(new TableCellEditor() {

            @Override

            public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {

                if (isSelected) {

                    jb.addActionListener(new ActionListener() {

                        @Override

                        public void actionPerformed(ActionEvent e) {

                             jTable = (JTable) e.getSource();

                        int modelRow = Integer.valueOf(e.getActionCommand());

                        ((DefaultTableModel) jTable.getModel()).removeRow(modelRow);

                        }

                    });

                }

                return jb;

            }

We can do it like in below sample program. We can write a custom renderer + editor which simply returns a JButton as the renderer/editor component. Notice that row index is stored in a field in the editor.

import javax.swing.*;

import javax.swing.event.CellEditorListener;

import javax.swing.table.*;

import java.awt.Component;

import java.awt.event.*;

import java.util.EventObject;



public class ButtonInTable {



  public static void main(String args) {



    DefaultTableModel tableModel = new DefaultTableModel(

        new Object {

            {"aa", "aaa", ""},

            {"bb", "bbb", ""},

            {"cc", "ccc", ""},

            {"dd", "ddd", ""},

            {"ee", "eee", ""}},

        new Object {"Column 1", "Column 2", " "});

    JTable table = new JTable(tableModel);

    table.getColumn(" ").setCellRenderer(new RendererAndEditor(table));

    table.getColumn(" ").setCellEditor(new RendererAndEditor(table));



    JFrame f = new JFrame();

    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    f.getContentPane().add(new JScrollPane(table));

    f.setBounds(300, 200, 400, 300);

    f.setVisible(true);

  }

}



class RendererAndEditor implements TableCellRenderer, TableCellEditor {



  private JButton button;

  private int row;



  RendererAndEditor(JTable table) {

    button = new JButton("Delete");

    button.addActionListener(new ActionListener() {

      @Override

      public void actionPerformed(ActionEvent e) {

        DefaultTableModel tableModel = (DefaultTableModel) table.getModel();

        tableModel.removeRow(row);

      }

    });

  }



  @Override

  public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,

                                                 boolean hasFocus, int row, int column) {

    return button;

  }



  @Override

  public java.awt.Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row,

                                                        int column) {

    this.row = row;

    return button;

  }



  @Override

  public Object getCellEditorValue() {

    return null;

  }



  @Override

  public boolean isCellEditable(EventObject anEvent) {

    return true;

  }



  @Override

  public boolean shouldSelectCell(EventObject anEvent) {

    return true;

  }



  @Override

  public boolean stopCellEditing() {

    return true;

  }



  @Override

  public void cancelCellEditing() { }



  @Override

  public void addCellEditorListener(CellEditorListener l) { }



  @Override

  public void removeCellEditorListener(CellEditorListener l) { }

}
