如何通过python从HTML表中按颜色删除列

Question

我在html表下面，并且我想删除所有没有背景的列：白色单元格

soup = BeautifulSoup(htmlbody, 'html.parser')
table1 = soup.find_all('table')[3]
print(table1)

<table border="0" cellpadding="0" cellspacing="0" class="MsoNormalTable" style="background:#F6F6F6;border-collapse:collapse"><tr style="vertical-align:center"><td style="border:solid windowtext

Answer 1

请尝试删除具有该样式的tds：

for t in table1.findAll("td"):
    if "background:white" in t["style"]:
        t.decompose()

要删除tds具有该样式的列，可以结合使用BeautifulSoup和pandas：

from bs4 import BeautifulSoup
import pandas as pd

soup = BeautifulSoup(htmlbody, 'html.parser')
table1 = soup.find_all('table')[3]

cols = set([])
for tr in table1.findAll("tr"):
    for i, td in enumerate(tr.findAll("td")):
        if "background:white" in td["style"]:
            cols.add(i)

df = pd.read_html(table1)
df = df[0]
df.drop(df.columns[list(cols)], axis=1, inplace=True)

希望我已经理解您的要求。
