Pandas html: Don't truncate long values

Question

I understand that pandas does cut-off long elements. However, why does it do that in the html output?

import pandas as pd
df = pd.DataFrame(columns=['url'], index=[0])
df['url'] = 'd12dn1928d1n298dn18d9n219d8n18n118219d8n21e12903e21kj9012j9301j2391023j209d12dn1928d1n298dn18d9n219d8n18n118219d8n21e12903e21kj9012j9301j2391023j209d12dn1928d1n298dn18d9n219d8n18n118219d8n21e12903e21kj9012j9301j2391023j209d12dn1928d1n298dn18d9n219d8n18n118219d8n21e12903e21kj9012j9301j2391023j209d12dn1928d1n298dn18d9n219d8n18n118219d8n21e12903e21kj9012j9301j2391023j209'
In [2]: df
Out[2]: 
                                                 url
0  d12dn1928d1n298dn18d9n219d8n18n118219d8n21e129...

In [3]: df.to_html()
Out[3]: u'<table border="1" class="dataframe">\n  <thead>\n    <tr style="text-align: right;">\n      <th></th>\n      <th>url</th>\n    </tr>\n  </thead>\n  <tbody>\n    <tr>\n      <th>0</th>\n      <td>d12dn1928d1n298dn18d9n219d8n18n118219d8n21e129...</td>\n    </tr>\n  </tbody>\n</table>'

even in the html output (where it is obvious that it won't fit the screen width), the column value is truncated. How can I force pandas to not truncate, both with and without html?

You can turn off the truncating display option with:

pd.set_option('display.max_colwidth', None)

or before Pandas 1.0,

pd.set_option('display.max_colwidth', -1)
