[英]How do I set the column width when using pandas.DataFrame.to_html?
I have read this , but I am still confused about how I set the column width when using pandas.DataFrame.to_html
.我已阅读此内容,但我仍然对使用pandas.DataFrame.to_html
时如何设置列宽感到困惑。
import datetime
import pandas
data = {'Los Angles': {datetime.date(2018, 9, 24): 20.5, datetime.date(2018, 9, 25): 1517.1},
'London': {datetime.date(2018, 9, 24): 0, datetime.date(2018, 9, 25): 1767.4},
'Kansas City': {datetime.date(2018, 9, 24): 10, datetime.date(2018, 9, 25): 1.4}}
df = pandas.DataFrame(data=data)
html = df.to_html()
The above code results in :上面的代码导致:
How do I go about forcing the column width so that they are the same?如何强制列宽使它们相同?
Try this:尝试这个:
import datetime
import pandas
data = {'Los Angles': {datetime.date(2018, 9, 24): 20.5, datetime.date(2018, 9, 25): 1517.1},
'London': {datetime.date(2018, 9, 24): 0, datetime.date(2018, 9, 25): 1767.4},
'Kansas City': {datetime.date(2018, 9, 24): 10, datetime.date(2018, 9, 25): 1.4}}
df = pandas.DataFrame(data=data)
pandas.set_option('display.max_colwidth', 40)
html = df.to_html()
I find it better to use the set_table_attributes function.我发现使用 set_table_attributes 函数更好。 You are then able to set eg a CSS-class to the table.然后,您可以为表格设置一个 CSS 类。 In case you have many tables on your output it is much better readable.如果您的输出中有很多表,则它的可读性会更好。
import datetime
import pandas
data = {'Los Angles': {datetime.date(2018, 9, 24): 20.5, datetime.date(2018, 9, 25): 1517.1},
'London': {datetime.date(2018, 9, 24): 0, datetime.date(2018, 9, 25): 1767.4},
'Kansas City': {datetime.date(2018, 9, 24): 10, datetime.date(2018, 9, 25): 1.4}}
df = pandas.DataFrame(data=data)
html = df.set_table_attributes('class="table-style"').to_html()
Your CSS could look something like that:你的 CSS 可能看起来像这样:
.table-style {
width: 100%;
}
.table-style td {
width: 100px;
}
另一种选择是
df.style.set_table_styles([dict(selector='th', props='min-width: 60px;'),])
