QT (35) - operate excel qxlsx qaxobject

Reading and writing EXCEL It's a routine operation .QT5 Previous versions use QAxObject operation EXCEL, The disadvantage is that the system must be equipped with OFFICE perhaps WPS.QT5 You can use it Qxlsx 了 , The advantage is that the system does not need to be installed OFFICE perhaps WPS.
Use Qxlsx There are two ways ：
1. hold bin,lib,include Join the system environment
2. Directly into the project . I prefer to join the project directly . The second method is given in this paper .
1. Download library files
2. Create project
3. Copy the library file to the project
4. Modify the configuration .pro file + Add header reference
