python - pandas to_latex() escapes mathmode

Question

pandas to_latex() methode seems to be a convenient way to convert bigger tabulars into into latex code. However, writing math mode, the $ seems to get escaped.

An example:

import pandas as pd
import numpy as np

table=np.asarray([['$x^2$',3]])
df=pd.DataFrame(table[:,1], columns=['value'], index=table[:,0])
print(df.to_latex(encoding='utf-8'))

output:

egin{tabular}{ll}
oprule
{} & value \
midrule
$xextasciicircum2$ &     3 \
ottomrule
end{tabular}

Is there a way to prevent this from happening?

Answer 1

Yes, the method's escape parameter is set to True by default. You can change it to False:

print(df.to_latex(encoding='utf-8', escape=False))

egin{tabular}{ll}
oprule
{} & value \
midrule
$x^2$ &     3 \
ottomrule
end{tabular}
