BUG: hrules and clines in .to_latex() draw two lines at bottom of table #49723
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
df = pd.DataFrame({'A': ['a', 'a', 'b'], 'B': ['a', 'b', 'a']})
df = df.groupby(['A', 'B']).size().to_frame()
print(
df.style.to_latex(
hrules=True,
clines='all;data'
)
)Issue Description
The code above produces the following latex code (I added latex preamble).
\documentclass[12pt,letterpaper]{article}
\usepackage{booktabs}
\usepackage{multirow}
\begin{document}
\begin{tabular}{llr}
\toprule
& & 0 \\
A & B & \\
\midrule
\multirow[c]{2}{*}{a} & a & 1 \\
\cline{2-3}
& b & 1 \\
\cline{1-3} \cline{2-3}
b & a & 1 \\
\cline{1-3} \cline{2-3}
\bottomrule
\end{tabular}
\end{document}which gives
You can see that there are two lines at the bottom of the table clines and \bottomrule.
Expected Behavior
In this example, to make the table more readable, it is preferred to use both hrules and clines. I don't know if there is something you can add in the latex preamble. One idea might be just let hrules to accept a list so that a user could pass ['toprule', 'midrule'] to avoid the bottomrule.
