我如何從jtable中刪除指定的行？

我有一個JTable，裏面有一些信息。現在我想從中刪除一個指定的行，但它有例外。我如何從jtable中刪除指定的行？

我寫了下面的代碼：

jtable table = new jtable(model); 

model.setDataVector(str2, str1); 

model.fireTableRowsDeleted(row, row); 
    model.removeRow(row); 


//str2,str1 are verctor

是什麼問題呢？

可以粘貼你如何創建表以及刪除該行的代碼？ – harshit 2011-04-10 20:44:48

java.lang.ArrayIndexOutOfBoundsException: 0 >= 0是一個非常清楚的指標，表已經是空的。

我確定這不是空的。 – 2011-04-10 20:49:12

@mehdi - 證明它;-) – kleopatra 2011-04-10 20:53:49

我可以在我的表中看到信息 – 2011-04-10 20:58:52

除了我的評論：model.fireSomething是而不是 soSomething的手段（並不意味着在模型外使用）。相反，調用model.removeRow（row） - 如果具體實現支持，則爲f.i. DefaultTableModel - 一切都將簡單地工作（假設該行是有效的行索引）。

附錄：吉姆是完全正確的 - stackstrace表明，該模型是空
