问题:df.to_html()
的输出是一个简单的html表,看起来不多:
与此同时,Jupyter笔记本中数据框的视觉表现要好得多,但如果有一种简单的方法可以复制它,我还是找不到它。
我知道应该可以通过摆弄df.style
来生成一个更美观的表格,但在我开始学习CSS之前,是否有人已经编写了一个函数来执行此操作?
答案 0 :(得分:5)
考虑我的数据框df
df = pd.DataFrame(np.arange(9).reshape(3, 3), list('ABC'), list('XYZ'))
df
X Y Z
A 0 1 2
B 3 4 5
C 6 7 8
我从我的jupyter笔记本上撕下了这种风格
my_style = """background-color: rgba(0, 0, 0, 0);
border-bottom-color: rgb(0, 0, 0);
border-bottom-style: none;
border-bottom-width: 0px;

border-image-outset: 0px;
border-image-repeat: stretch;

我是从my post
得到的def HTML_with_style(df, style=None, random_id=None):
from IPython.display import HTML
import numpy as np
import re
df_html = df.to_html()
if random_id is None:
random_id = 'id%d' % np.random.choice(np.arange(1000000))
if style is None:
style = """
<style>
table#{random_id} {{color: blue}}
</style>
""".format(random_id=random_id)
else:
new_style = []
s = re.sub(r'</?style>', '', style).strip()
for line in s.split('\n'):
line = line.strip()
if not re.match(r'^table', line):
line = re.sub(r'^', 'table ', line)
new_style.append(line)
new_style = ['<style>'] + new_style + ['</style>']
style = re.sub(r'table(#\S+)?', 'table#%s' % random_id, '\n'.join(new_style))
df_html = re.sub(r'<table', r'<table id=%s ' % random_id, df_html)
return HTML(style + df_html)
然后我实施
HTML_with_style(df, '<style>table {{{}}}</style>'.format(my_style))
您可以修改代码以转储html
def HTML_with_style(df, style=None, random_id=None):
import numpy as np
import re
df_html = df.to_html()
if random_id is None:
random_id = 'id%d' % np.random.choice(np.arange(1000000))
if style is None:
style = """
<style>
table#{random_id} {{color: blue}}
</style>
""".format(random_id=random_id)
else:
new_style = []
s = re.sub(r'</?style>', '', style).strip()
for line in s.split('\n'):
line = line.strip()
if not re.match(r'^table', line):
line = re.sub(r'^', 'table ', line)
new_style.append(line)
new_style = ['<style>'] + new_style + ['</style>']
style = re.sub(r'table(#\S+)?', 'table#%s' % random_id, '\n'.join(new_style))
df_html = re.sub(r'<table', r'<table id=%s ' % random_id, df_html)
return style + df_html
现在
HTML_with_style(df, '<style>table {{{}}}</style>'.format(my_style))

您还可以在笔记本顶部添加以下Raw NBConvert单元格:
<link rel="stylesheet" href="https://cdn.jupyter.org/notebook/5.1.0/style/style.min.css">
NBConvert似乎无法将这些样式添加到导出的HTML中。上面的行将明确添加它们。

经过一些研究,我发现了最漂亮和最简单的解决方案是 https://pypi.org/project/pretty-html-table/
import pandas as pd
from pretty_html_table import build_table
df = pd.DataFrame(np.arange(9).reshape(3, 3), list('ABC'), list('XYZ'))
html_table_blue_light = build_table(df, 'blue_light')
print(html_table_blue_light)
with open('styled_table.html', 'w') as f:
f.write(html_table_blue_light)
