Jtable作爲Jtree節點

Question

我知道你可以創建一個table and add a JTree as a column。但我想要做的是完全相反。

檢查圖像，並告訴我這是否可能。謝謝！

UPDATE：

通過使用MKorbel的代碼，並通過隨機列數用下面的代碼：

@Override 
public int getColumnCount() { 
    int i = (int) (Math.random()* 10.0); 
    if (i%2 ==0) 
     return 2; 
    else 
     return 3; 
} 

我能夠獲得下面的圖片：

Answer 1

1）I沒有解決在RendererisLeaf()和Editor不知何故

2）如果我把JScrollPane與JTable到Node直接（不使用JPanel作爲parent）然後JTree View未正確START_UP用於後呈現更多信息請看我的問題Put JTable in the JTree
