求救！JTable加载的单元格在点击之后消失...

Question

为了实现表格的多行和多列，我用tablecellrenderer把一个jTable的单元格（cell)改成加在JScrollPane里的cellTable,然后用了celleditor来实现对cellTable的访问。
但是遇到的问题是--在点击这个cellTable后，再点击jTable的其他单元，这个cellTable就消失了！而且出现下列的异常：Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: adding container's parent to itself

at java.awt.EventDispatchThread.run(EventDispatchThread.java:110)下面是我写的RENDERER和EDITOR：//这个是重写的RENDERER，经测试没有问题import java.awt.Component;
import java.awt.Font;import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.UIManager;
import javax.swing.table.TableCellRenderer;public class JTableHeadCellRenderer extends JScrollPane implements TableCellRenderer {   private Font tableFont = new Font("SansSerif", Font.PLAIN, 14);

//t.setBorder(UIManager.getBorder("TableHeader.cellBorder"));
t.setFont(tableFont);
     setViewportView(t);
    }
    return this;
  }
}//下面是重写的EDITOR
import java.awt.Component;import javax.swing.DefaultCellEditor;
import javax.swing.JCheckBox;
import javax.swing.JTable;public class JScrollPaneEditor extends DefaultCellEditor { private JTable table;

public JScrollPaneEditor(JCheckBox checkBox) {
super(checkBox);
} public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column) {
if (value != null){
table = (JTable) value;
}
return table;
} public Object getCellEditorValue() {
return table;
  }
}经过分步测试，问题完全出在重写的CELLEDITOR上，但却找不到解决的办法，急请大家赐教！

Answer 1

忘了说了,这个RENDERER和EDITOR是通过对jTable的列(column)起作用的.具体如下:DefaultTableModel dm = new DefaultTableModel();     
dm.setDataVector(new Object[][]{{getNameTable(),"",""}}, new Object[]{"name","Adress", "Company"});
JTable jTable = new JTable(dm); 
jTable.setRowHeight(200);
jTable.setShowGrid(false);
jTable.getColumn("name").setCellRenderer(new JTableHeadCellRenderer());
jTable.getColumn("name").setCellEditor(new JScrollPaneEditor(new JCheckBox()));getNameTable()得到的是一个12X3的表格,在这里它被加载到jTable第一列第一行的单元格.我知道问题出在JScrollPaneEditor的public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column)方法的重写上,但就是不知道该怎么改.
 
还请大家帮忙看看

Answer 2

public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column) {
if (value != null){
if (isSelected)
this.table = (JTable) value;
}
return this.table;
}
问题解决了!:D
是自己犯浑,居然忘了这个方法里有重名的参数,导致每次加载的都是自己本身,所以出错.看来还是要好好学啊.
多谢顶贴的两位朋友.
再看看,如果这个程序没问题了我就散分^^

出了异常首先看异常信息，是很有用的。
