Pandas to_html cannot apply style

[zljubisic at gmail.com]

Hi,

the following code never applies style and I cannot figure out why.
Can someone please help?

import pandas as pd

def function2(row):
    if row.A == True:
        color = '#FF0000'
    else:
        color = '#00FF00'

    background_color = 'background-color: {}'.format(color)

    return [background_color] * len(row.values)

idx = pd.date_range('01.01.2017', periods=7, freq='D')
A = [False, True, True, False, True, False, True]
B = np.random.randn(7)
C = np.random.randn(7)

data = { 'A' : [False, True, True, False, True, False, True],
        'B' : np.random.randn(7),
        'C' : np.random.randn(7)
        }

df = pd.DataFrame(data, index=idx)

df.style.apply(function2, axis=1)

html = df.style.render()

if '#FF0000' in html or '#00FF00' in html:
    print('style applied')
else:
    print('style not applied')

Regards.
