NX二次开发-使用libxl读写EXCEL

最近这一段身体不舒服，所以一直没写博客，晚上都在躺床上看斗鱼直播。看看电视剧大宅门，看看女主播跳舞，偶尔还看看七龙珠。

之前写过OLE/COM组件方式读写EXCEL，前几天做了一个C++ QT的应用程序，当时发现在QT项目里不能用OLE，网上搜别人都是拿QT的EXCEL库去弄的，

我没研究那么深，还不会。后来搜到了LIBXL，这个也可以做EXCEL读写，而且优点是本地不需要安装OFFICE都可以读写EXCEL，这一点是OLE所不具备的，

而且库是人家封装好的了，直接调用封装现成的方法就行了。配置开发环境也非常简单，读写速度特别快。但是也有缺点，缺点是这个是付费的，当然CSDN上面也有破解的库。还有就是可能不支持多线程。

注意事项：OLE行列是从1开始的，LIBXL行列是从0开始的。
