pandas to_latex()退出mathmode

问题描述

熊猫to_latex()方法似乎是将较大的表格转换为乳胶代码的便捷方法.但是，在编写数学模式时，$似乎被转义了.

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.

一个例子:

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'))

输出:

\begin{tabular}{ll}
\toprule
{} & value \\
\midrule
\$x\textasciicircum2\$ &     3 \\
\bottomrule
\end{tabular}

有办法防止这种情况发生吗?

Is there a way to prevent this from happening?

推荐答案

是的，方法的转义参数默认设置为True.您可以将其更改为False:

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))

\begin{tabular}{ll}
\toprule
{} & value \\
\midrule
$x^2$ &     3 \\
\bottomrule
\end{tabular}
