java - 如何从 jtable 中删除指定行？

Question

我有一个 JTable，里面有一些信息。现在我想从中删除指定行，但它有异常。

我写了下面的代码:

jtable table = new jtable(model);

 model.setDataVector(str2, str1);

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


//str2,str1 are verctor

问题是什么？

Answer 1

java.lang.ArrayIndexOutOfBoundsException: 0 >= 0 非常清楚地表明该表已为空。
