请问如何往JTable的单元格中添加一个按钮？

[topscien]

如题，为什么我写的代码单元格内却是一大串字符串呢？

Vector<Object> v ;
JButton button ;
v = new Vector<Object>() ;
button = new JButton("登记") ;
v.add("name") ;
v.add("type") ;
v.add((JButton)button) ;
((DefaultTableModel)table.getModel()).addRow(v) ;
希望高手们能为我解答一下~~

public class TestJTable {
	public static JTable table;	
	public static void main(String[] args) {
		JFrame frame = new JFrame("Test Table Header");
		table = new JTable(6,6);		
		TableRender render = new TableRender();
		table.setRowHeight(20);
		TableEditor editor = new TableEditor(new JTextField());
		table.getColumnModel().getColumn(1).setCellRenderer(render);
		table.getColumnModel().getColumn(1).setCellEditor(editor);
		editor.setClickCountToStart(0);
		JScrollPane pane = new JScrollPane(table);			
		frame.setContentPane(pane);
		frame.setPreferredSize(new Dimension(500,500));
		frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
		frame.pack();
		frame.setVisible(true);		
	}
}

你要改的应该是Render，和TableUI，不是改model
