does not reproduce for me, please tell me:

• version of tabulate, and
• version of wcwidth

verify:

>>> import wcwidth; wcwidth.wcswidth('信用减值损失')
12

[playgithub]

version info:

• python 3.8.5
• tabulate 0.8.7
• wcwidth 0.2.5

test:

>>> import wcwidth; wcwidth.wcswidth('信用减值损失')
12

the problem seems here:

>>> import wcwidth; wcwidth.wcswidth('—')
1

it should be 2

Thanks for clarifying, I’ll look into it maybe during it between holidays, a bit busy but any PR always welcome thanks for the report !!!

Just more evidence

Above are tested in Visual Studio 2019 on Windows.

Tested in vscode on Linux, no problem.

Tested in pycharm on Linux

When changed to a specific font, Inconsolata, it aligned perfectly.
The problem might be caused by font, for "—", the width might be 1 or 2 that depends on the font.

BTW, pycharm output font is the the same as editor font
