我有一个通过单击按钮刷新的jtable。但每次单击刷新按钮时，都会再次显示相同的结果。
*例如，我第一次点击刷新jtable上显示的结果是：
名称
姓
*我第二次点击刷新结果是：
名称
姓氏
名称
姓
同样的结果是重复的。 即使我多次单击刷新按钮，我应该如何获得一次结果？

答案 0 :(得分：0)
当您刷新表格时，您正在复制模型中的项目。你能告诉我们你在点击刷新时执行的代码吗？
您的刷新按钮应该在JTable实例上调用fireTableDataChanged()。这应该是全部，如果您更新模型，表格应该正确更新。
答案 1 :(得分：0)
我必须删除行并再次显示
int rowCount = model.getRowCount();
for (int i = rowCount - 1; i >= 0; i--) {
model.removeRow(i);
}
