如何更改 pandas DataFrame标头的样式? [英] How can I change the styles of pandas DataFrame headers?

问题描述

我有以下生成HTML表的Python脚本.现在，我想更改表格的某些样式，但是在更改标题的字体大小时遇到​​问题.

I have the following Python script which generates a HTML table. Now I want to change some styles of the table, but I'm having problems with changing the font sizes of the headers.

import pandas as pd

df = pd.DataFrame({'col1': [1, 2, 3, 4]})

html = (df.style
        .set_table_styles({'selector': 'th', 'props': [('font-size', '5pt')]})
        .set_properties(**{'font-size': '10pt'}).render())

f = open('test.html', 'wb')
f.write(html)

推荐答案

我发现我需要将参数作为列表传递给Styler.set_table_styles().现在，它可以使用以下代码.

I've found out I need to pass a parameter as a list to Styler.set_table_styles(). It's now working with the following code.

html = (df.style
        .set_table_styles([{'selector': 'th', 'props': [('font-size', '5pt')]}])
        .set_properties(**{'font-size': '10pt'}).render())
