How can I change the styles of pandas DataFrame headers?
提问by Han
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.
我有以下生成 HTML 表格的 Python 脚本。现在我想更改表格的某些样式，但是我在更改标题的字体大小时遇到了问题。
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)

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.
我发现我需要将参数作为列表传递给Styler.set_table_styles(). 它现在使用以下代码。
html = (df.style
.set_table_styles([{'selector': 'th', 'props': [('font-size', '5pt')]}])
.set_properties(**{'font-size': '10pt'}).render())
