Code Sample, a copy-pastable example if possible

import pandas as pd
df = pd.DataFrame({'acol':['a', 'aa'], 'bcol':['b', 'bb']}, index=['row1', 'row2'])
print df.to_latex(bold_rows=True)
{} & acol & bcol \\
row1 &    a &    b \\
row2 &   aa &   bb \\

Problem description

Despite bold_rows is documented to be an option of to_latex() and to be True by default, in reality, this option has no effect. Moreover, the current behaviour corresponds with what would be expected for bold_rows=False and is thus in contrast with the documented default 'bold_rows=True' behaviour.

Expected Output

{} & acol & bcol \\
\textbf{row1} &    a &    b \\
\textbf{row2} &   aa &   bb \\

Output of pd.show_versions()
