《Qt5+QAxObject操作Excel》

Qt5操作Excel需要用到QAxObject类，还需要在pro文件中添加QT+=axcontainer。

QAxObject类

The QAxObject class provides a QObject that wraps a COM object. 

Header:	#include
qmake:	QT += axcontainer
Inherits:	QObject and QAxBase
Inherited By:	QAxScriptEngine

新建项目 

打开Qt，新建一个Qt Widgets Application项目，转到设计师模式，从左侧工具栏添加两个PushBotton控件到窗口上，调整PushBotton控件的大小，分别为两个PushBotton控件添加槽并修改按钮名字为创建Excel和添加数据，具体做法如下：

选中按钮，右键，转到槽...，选择clicked()，OK

添加代码

选择项目文件名，右键，选择添加新文件，类名为Exchange，然后分别添加代码如下：
