Description
Pandas version checks
-
I have checked that this issue has not already been reported.
-
I have confirmed this bug exists on the latest version of pandas.
-
I have confirmed this bug exists on the main branch of pandas.
Reproducible Example
import pandas as pd
print(pd.__version__)
# Expected Output
col1 = 'TEST'
col2 = 'PANDAS'
col3 = 'to_string'
print(f'{col1:<6s} {col2:<7s} {col3:<10s}')
# to_string output
df = pd.DataFrame([{'col1': 'TEST', 'col2': 'PANDAS',
'col3': 'to_string'}])
d = {'col1': '{:<6s}'.format,
'col2': '{:<7s}'.format,
'col3': '{:<10s}'.format}
print(df.to_string(index=False, header=False,
formatters=d))Issue Description
Extra spaces get added when using to_string() in pandas 2.0 and the main branch.
Was advised in Slack to create a new issue, as those bug reports are quite old.
Expected Behavior
Issue not present in pandas 1.5.3.
