Openpyxl更改content_type.xml，并且需要在打开XLSX之前对其进行修复

Question

如果我加载工作簿，请对其进行更改，然后将其另存为单独的文档，当我尝试在Excel中打开此新文档时出现错误。如果单击“是”（修复文件），则可以将其打开，并且所有数据均按预期存在。并非所有工作簿都发生这种情况。我很确定它与工作簿中的某些格式有关，但我不知道是哪一种格式。

Excel error message

如果我加载工作簿并且不进行更改，但是将其另存为单独的文档，则打开时不会出现错误。

查看新的（损坏的）文件和原始文件的content_type.xml，似乎Openpyxl没有使用与原始文件相同的ContentType / PartName。

代码：

import openpyxl
import time

wb_name = 'test.xlsx'
new_book = openpyxl.load_workbook(wb_name)
new_book.worksheets[2].insert_cols(3, 2)
output_file = "test-%s.xlsx" % time.strftime("%Y%m%d-%H%M%S")
new_book.save(filename=output_file)

原始文件的content_types.xml：
