to_string formatters not as expected when header=False · Issue #16839 · pandas-dev/pandas (original) (raw)

Code Sample, a copy-pastable example if possible

import pandas df = pandas.DataFrame({'c': 1, 'd': 2.3}, index=[0], ) formats = {'c': '{: 10d}', 'd': '{: 2.5f}'} formatters = {k: v.format for k, v in formats.items()} print(df.to_string(formatters=formatters, index=False, header=True)) print(df.to_string(formatters=formatters, index=False, header=False))

Problem description

I expect the spaces in the beginning, but they don't appear when header=False.

Expected Output
