how to add checkbox and combobox in table cell?

Question

I am creating one form which contain table and some buttons.

A picture is worth a thousand words:

Answer 1

includeColumn.setCellEditor(new DefaultCellEditor(new JCheckBox()));

• there no reason to use or write Renderer and Editor for JCheckBox in the JTable, put there true / false, because JTable has built_in support for JCheckbox as Renderer and Editor too

• override proper column, returns Boolean.Class

• for JComboBox to read Using a Combo Box as an Editor

• every data are stored in XxxTableModel, and by using DefaultTableModel are events automatically displayed in the JTables view

• all updates to the XxxTableModel must be done on Event Dispatch Thread

Answer 2

Here is combo cell insets replicate demo:

import java.awt.*;
import java.awt.event.*;
import java.util.EventObject;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;

public class ComboCellInsetsDemo {
  public JComponent makeUI() {
    String[] columnNames = {"Name", "Check", "Condition"};
    Object[][] data = {
      {"bbb", false, "="}, {"aaa", true, "<"}
    };
    DefaultTableModel model = new DefaultTableModel(data, columnNames) {
      @Override public Class<?> getColumnClass(int column) {
        return getValueAt(0, column).getClass();
      }
    };
    JTable table = new JTable(model);
    table.setRowHeight(36);
    table.setAutoCreateRowSorter(true);
    TableColumn column = table.getColumnModel().getColumn(2);
    column.setCellRenderer(new ComboBoxCellRenderer());
    column.setCellEditor(new ComboBoxCellEditor());
    return new JScrollPane(table);
  }
  public static void main(String[] args) {
    EventQueue.invokeLater(new Runnable() {
      @Override public void run() {
        createAndShowGUI();
      }
    });
  }
  public static void createAndShowGUI() {
    JFrame f = new JFrame();
    f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    f.getContentPane().add(new ComboCellInsetsDemo().makeUI());
    f.setSize(320, 240);
    f.setLocationRelativeTo(null);
    f.setVisible(true);
  }
}
