Java 中在JTable的第一列放入单选按钮

Question

要求：  
    JTable的行数是动态生成，如果(int line)传入n则生成n个单选按钮
    请给源码，谢谢

Answer 1

说实话没太明白想要一个什么样的效果。
简单写了一个，仅供参考。
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.JRadioButton;
import javax.swing.ButtonGroup;
import java.awt.*;
import java.util.*;
public class TableTest extends JFrame {
public TableTest () {
Vector cell ;
Vector row = new Vector(); DefaultTableModel tableModel = new DefaultTableModel(); String[] tableHeads = {"序号","姓名", "年龄", "单选框"};
Vector tableHeadName = new Vector();
for (int i = 0; i < tableHeads.length; i++) {
tableHeadName.add(tableHeads[i]);
}
for (int i = 1; i <= 30; i++) {
cell = new Vector();
cell.add(i);
cell.add("曹操"+i);
cell.add(""); cell.add(new JRadioButton("",true));
row.add(cell);
} tableModel.setDataVector(row, tableHeadName);
JTable table = new JTable (tableModel); TableColumn column;
column=table.getColumnModel().getColumn(3);
                column.setCellRenderer(new   MyTableCellRenderer());
  
   JScrollPane scrollPane = new JScrollPane(table);
this.getContentPane().add(scrollPane);
this.setTitle("Table表格的例子");
this.setSize(600, 300);
this.setVisible(true);
}
public static void main(String[] args) {
TableTest test = new TableTest ();
}
}class MyTableCellRenderer extends JRadioButton implements TableCellRenderer{   
public MyTableCellRenderer() {   
         super();   
}   
      
public Component getTableCellRendererComponent(JTable table,Object value,boolean isSelected,boolean hasFocus,int row,int column)   {   
if(hasFocus){   
               this.setSelected(true); 
                }else{   
this.setSelected(false); 
                }   
        return   this;   
        }   
}
