Export a LaTeX table from pandas DataFrame
提问by PlagTag
Is there an easy way to export a data frame (or even a part of it) to LaTeX?
有没有一种简单的方法可以将数据框（甚至是其中的一部分）导出到 LaTeX？
I searched in google and was only able to find solutions using asciitables.
我在谷歌搜索，只能找到使用 asciitables 的解决方案。

DataFrames have a to_latex(see the pandas docs) method:
DataFrames 有一个to_latex（参见pandas 文档）方法：
In [42]: df = pd.DataFrame(np.random.random((5, 5)))
In [43]: df
Out[43]:
0 1 2 3 4
0 0.886864 0.518538 0.359964 0.167291 0.940414
1 0.834130 0.022920 0.265131 0.059002 0.530584
2 0.648019 0.953043 0.263551 0.595798 0.153969
3 0.207003 0.015721 0.931170 0.045044 0.432870
4 0.039886 0.898780 0.728195 0.112069 0.468485
In [44]: print df.to_latex()
\begin{tabular}{|l|c|c|c|c|c|c|}
\hline
{} & 0 & 1 & 2 & 3 & 4 \
\hline
0 & 0.886864 & 0.518538 & 0.359964 & 0.167291 & 0.940414 \
1 & 0.834130 & 0.022920 & 0.265131 & 0.059002 & 0.530584 \
2 & 0.648019 & 0.953043 & 0.263551 & 0.595798 & 0.153969 \
3 & 0.207003 & 0.015721 & 0.931170 & 0.045044 & 0.432870 \

\hline
\end{tabular}
You can simply write this to a tex file.
您可以简单地将其写入 tex 文件。
By default latex will render this as:
默认情况下，乳胶会将其呈现为：
Note: the to_latex(see the pandas docs) method offers several configuration options.
注意：（to_latex参见pandas 文档）方法提供了几个配置选项。

Just write to a textfile. It's no magic:
只需写入文本文件。这不是魔术：
import pandas as pd
df = pd.DataFrame({"a":range(10), "b":range(10,20)})
with open("my_table.tex", "w") as f:
f.write("\begin{tabular}{" + " | ".join(["c"] * len(df.columns)) + "}\n")
for i, row in df.iterrows():
f.write(" & ".join([str(x) for x in row.values]) + " \\\n")
f.write("\end{tabular}")

If you want to save it:
如果你想保存它：
with open('mytable.tex', 'w') as tf:
tf.write(df.to_latex())
