pandas to_html using the .style options or custom CSS?
I was following the style guide for pandas and it worked pretty well.
How can I keep these styles using the to_html command through Outlook? The documentation seems a bit lacking for me.
(df.style
.format(percent)
.applymap(color_negative_red, subset=['col1', 'col2'])
.set_properties(**{'font-size': '9pt', 'font-family': 'Calibri'})
.bar(subset=['col4', 'col5'], color='lightblue'))
import win32com.client as win32
outlook = win32.Dispatch('outlook.application')
mail = outlook.CreateItem(0)
mail.Subject = subject_name
mail.HTMLbody = ('<html><body><p><body style="font-size:11pt;
font-family:Calibri">Hello,</p> + '<p>Title of Data</p>' + df.to_html(
index=False, classes=????????) '</body></html>')
mail.send
The to_html documentation shows that there is a classes command that I can put inside of the to_html method, but I can't figure it out. It also seems like my dataframe does not carry the style that I specified up top.
If I try:
df = (df.style
.format(percent)
.applymap(color_negative_red, subset=['col1', 'col2'])
.set_properties(**{'font-size': '9pt', 'font-family': 'Calibri'})
.bar(subset=['col4', 'col5'], color='lightblue'))
Then df is now a Style object and you can't use to_html.
Edit - this is what I am currently doing to modify my tables. This works, but I can't keep the cool features of the .style method that pandas offers.
email_paragraph = """
<body style= "font-size:11pt; font-family:Calibri; text-align:left; margin: 0px auto" >
"""
email_caption = """
<body style= "font-size:10pt; font-family:Century Gothic; text-align:center; margin: 0px auto" >
"""
email_style = '''<style type="text/css" media="screen" style="width:100%">
table, th, td {border: 0px solid black; background-color: #eee; padding: 10px;}
th {background-color: #C6E2FF; color:black; font-family: Tahoma;font-size : 13; text-align: center;}
td {background-color: #fff; padding: 10px; font-family: Calibri; font-size : 12; text-align: center;}
</style>'''
Answer
Once you add style to your chained assignments you are operating on a Styler object. That object has a render method to get the html as a string. So in your example, you could do something like this:
html = (
df.style
.format(percent)
.applymap(color_negative_red, subset=['col1', 'col2'])
.set_properties(**{'font-size': '9pt', 'font-family': 'Calibri'})
.bar(subset=['col4', 'col5'], color='lightblue')
.render()
)
Then include the html in your email instead of a df.to_html().
