熊猫DataFrame.to_latex（）无法识别column_format

Question

I am creating latex tables from Pandas DataFrames using the .to_latex() command. According to its documentation it has a column_format keyword argument, but when I try to set it to 'cccc' I get an error:

to_latex() got an unexpected keyword argument 'cols_format'

Why does this happen?

EDIT: The error message I get is actually

TypeError: to_latex() got an unexpected keyword argument 'column_format'

Answer 1

关键字参数是column_format NOT cols_format 。
