Swing 中 Jtable的表头 放置一个 JTextField组件显示出来了，但是却输入不了？求大神告知：
代码1：
package com.njust.zht.test;

import java.awt.Component;

import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JComboBox;
import javax.swing.JTable;
import javax.swing.JTextField;
import javax.swing.table.TableCellRenderer;

public class MyHeaderButtonRenderer extends JTextField implements TableCellRenderer{

/**
*
*/
private static final long serialVersionUID = 1L;

@Override
public Component getTableCellRendererComponent( JTable table,Object value,boolean isSelected,boolean hasFocus,int row,int column ) {
// Boolean b = (Boolean) value;
// this.setSelected(b.booleanValue());
this.setEnabled(true);
this.setText("12345");

return this;
}

}

在描述器是不是不设置该列为只读属性了？
