QXlsx is unable to read the contents of xlsx files created by Openpyxl.

[lp92321]

Environment: Ubuntu 20.04, Qt5.14.1, Python3.8.10, Pip 20.0.2, Openpyxl3.0.9/Openpyxl3.1.5
In the above environment, I used Python to call openpyxl to create an xlsx file and write a string into it, then saved it as "openpyxl_create.xlsx". Afterwards, when I tried to read the content of openpyxl_create.xlsx using a Qt project with QXlsx, I found that the reading failed. Only after first saving the openpyxl_create.xlsx file as an Excel 2007-365 formatted xlsx file using LibreOffice Calc, was QXlsx able to read the file's content. This method yielded the same test results for both openpyxl3.0.9 and openpyxl3.1.5. I hope QXlsx can directly read and write files created by openpyxl and that openpyxl can directly read and write files created by QXlsx; that would be really cool.

Here is the Python script I wrote to generate an xlsx file：
import openpyxl
path = './exa.xlsx'
wb = openpyxl.Workbook()
sheet = wb.active
record_data = ['step','loss']
sheet.append(record_data)
wb.save(path)
wb.close()
