如何使用 python docx 更改表格中的线条粗细

Question

Line thickness 1 within a table

Line thickness 2 within a table

我目前正在尝试更改 Microsoft Word 文档中表格的线条粗细。该表的默认线条粗细为 1 pt，我正在尝试找到一种使用 python docx 将线条粗细更改为 2pt 的方法。

此处提供设置表格/单元格边框的文档：http://officeopenxml.com/WPtableBorders.php

我已经重用了现有的代码来设置表格单元格边框在这里回答https://stackoverflow.com/a/49615968/5736491 并修改它以设置单个表格属性。这将为表格中的所有边框设置统一属性，并将其存储在表格级别（而不是单个单元格级别）：
