Quarto 在格式化表格时忽略 LaTeX 命令

Question

我正在使用 quarto 和 python 渲染 PDF。我想在列标题中包含换行符，但编译文档时不会处理命令。我试过了：

import pandas as pd

# Create a DataFrame
data = {
    'Column 1\nLine 2': [1, 2, 3],
    'Column 2\nLine 2': [4, 5, 6]
}
df = pd.DataFrame(data)

# Convert DataFrame to LaTeX table
latex_table = df.to_latex(escape=False).replace('\\n', '\\\\')

display(Latex(df.to_latex(index=False)))

这只会导致列标题中出现反斜杠。

data = {
    'Column 1\nLine 2': [99, 2, 3],
    'Column 2\nLine 2': [4, 5, 6]
}
df = pd.DataFrame(data)

# Convert DataFrame to a tabulate table in LaTeX format
table_latex = tabulate(df, headers='keys', tablefmt='latex')

# Display the LaTeX table
display(Latex(table_latex))

这会产生一个没有附加符号的单行标题。

title: "wow"
format:
    pdf:
        documentclass: article
        keep-tex: false
        include-in-header:
            text: |
                \usepackage{makecell}
--

```{python}
data = {
    '\makecell{Column 1 \\ Line 2}': [88, 2, 3],
    '\makecell{Column 1 \n Line 2}': [4, 5, 6]
}
df = pd.DataFrame(data)

# Convert DataFrame to a tabulate table in LaTeX format
table_latex = tabulate(df, headers='keys', tablefmt='latex')

# Display the LaTeX table
display(Latex(table_latex))

单元格分别读作

\makecell{Column 1 \ Line 2}

和

\makecell{Column 2 Line 2}

。

我正在寻找任何允许列标题包含换行符的解决方案。四开版 1.5.53

经过更多探索，我找到了解决方案。

```{python}

import pandas as pd
from tabulate import tabulate
from IPython.display import display, Latex

data = {
    'Column 1 \\\ Line 2': [1, 2, 3],
    'Column 2 Line 2': [4, 5, 6]
}
df = pd.DataFrame(data)

with open("table.tex", "w") as f:
    f.write(latex_table)

print(latex_table)
```

```{=latex}
\input{table.tex}
```
