to_string formatters not as expected when header=False

[adamboche]

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.

u'c        d\n        1  2.30000'

'1  2.30000'

Expected Output

u'c        d\n        1  2.30000'

'         1  2.30000'
