mail html css,简单的HTML电子邮件：基本的CSS样式被剥离

我通过一个python脚本从linux机器上的命令行发送一封简单的电子邮件。我已经在电子邮件客户端中查找了CSS为什么会被更改、删除等问题的答案。然而，我似乎无法解决我看来很简单的问题。在

当我发送一封带有表格的简单HTML电子邮件时，随机td的风格就会被剥离。当我在浏览器中呈现相同的HTML时，它看起来很好。在

下面是python代码：#!/usr/bin/python

import os

import subprocess

def make_html_report(data, subject):

text = ''

text += '

'

text += ''

text += '

{0}'.format(subject)

text += ''

text += '

'

text += '

for row, line in enumerate(data):

tr_style = ""

if row == 0:

tr_style += "border-bottom:solid 1px #000000;"

text += '

'.format(tr_style)

for index, item in enumerate(line):

td_style = "border-right:solid 1px #000000;"

if row != 0:

if index == 1:

td_style += "text-align:right; padding-right:5px;"

if float(line[3]) < 0:

td_style += "color:#ff0000;"

if index != 1 or row == 0:

td_style += "text-align:center;"

text += '

{1}'.format(td_style, item)

text += '

'

text += '

'

text += '

'

text += ''

text += ''

print text

return text

def send_report(html_content, subject):

SENDMAIL = "/usr/sbin/sendmail" # sendmail location

p = os.popen("%s -t" % SENDMAIL, "w")

text = "From: {0}\nTo: {1}\nSubject: {2}\nContent-Type: text/html\nMIME-Version: 1.0\n\n{3}".format(

"me@example.com",

"me@example.com",

subject,

html_content

)

print "\n{0}".format(text)

p.write(text)

sts = p.close()

if __name__ == "__main__":

subject = "example subject"

data = [["head1","head2","head3","head4"], [1,2,3,4], [4,3,2,1], [8,7,6,4], [6,5,4,-5], [5,4,3,-2], [8,7,6,4], [6,5,4,-5], [5,4,3,-2]]

send_report(make_html_report(data, subject), subject)

我用了一个html检查器。一切都很好。但每当我发邮件时，都会发生一些或所有这些事情：

(1) td完全失去了他们的风格元素

(2) 在样式元素中插入一个随机空格，因此它不会呈现。示例：
