如何给jtable添加单选框

您好，可以使用JRadioButton作为单选框，然后将其添加到JTable的表格中，具体实现可以通过继承AbstractTableModel，重写getColumnClass方法，将对应列的Class设置为JRadioButton即可。具体代码实现如下：

import javax.swing.*;
import javax.swing.table.AbstractTableModel;

public class MyTableModel extends AbstractTableModel {
    
    private Object[][] rowData = {
            {"1", "option1"},
            {"2", "option2"},
            {"3", "option3"},
    };
    private String[] columnNames = {"ID", "Options"};
    private JRadioButton[][] radioButtons = new JRadioButton[rowData.length][1];
    
    @Override
    public int getRowCount() {
        return rowData.length;
    }
    
    @Override
    public int getColumnCount() {
        return columnNames.length;
    }
    
    @Override
    public Object getValueAt(int rowIndex, int columnIndex) {
        if (columnIndex == 0) {
            return rowData[rowIndex][columnIndex];
        } else {
            JRadioButton radioButton = radioButtons[rowIndex][columnIndex - 1];
            if (radioButton == null) {
                radioButton = new JRadioButton();
                radioButtons[rowIndex][columnIndex - 1] = radioButton;
            }
            return radioButton;
        }
    }
    
    @Override
    public String getColumnName(int column) {
        return columnNames[column];
    }
    
    @Override
    public Class<?> getColumnClass(int columnIndex) {
        if (columnIndex == 0) {
            return Integer.class;
        } else {
            return JRadioButton.class;
        }
    }
    
    public static void main(String[] args) {
        JFrame frame = new JFrame("JTable with JRadioButton");
        frame.setSize(400, 300);
        
        JTable table = new JTable(new MyTableModel());
        JScrollPane scrollPane = new JScrollPane(table);
        frame.add(scrollPane);
        
        frame.setVisible(true);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}
