Pandas DataFrame styler HTML display without index?

Question

I have a pandas dataframe, I'm using the df.style object to make it highlight odd-numbered rows, so:

def highlight_oddRow(s):
    return ['background-color: yellow' if s.name % 2 else '' for v in s]

table = pd.DataFrame(
    {'a': [3,9,8,0,2], 'b': [5,95, 9, 25,5], 'c': [23,54, 2, 3,5], 'row': [1, 2, 3, 4, 5]})

with open ('out.html','w') as out:
    print >> out, table.style.apply(highlight_oddRow, axis=1).render()

However, this always prints out the index. Is there a way to tell it not to do this?

Answer 1

Since this is the first question that popped up when I searched for this issue on Stack Overflow, I thought it would be good to share a recent development: on Nov-17 a PR was committed to the pandas repo that added the hide_index method to styler objects.

You can just call it before render:

def highlight_oddRow(s):
    return ['background-color: yellow' if s.name % 2 else '' for v in s]

table = pd.DataFrame(
    {'a': [3,9,8,0,2], 'b': [5,95, 9, 25,5], 'c': [23,54, 2, 3,5], 'row': [1, 2, 3, 4, 5]})

with open ('out.html','w') as out:
    print >> out, table.style.apply(highlight_oddRow, axis=1).hide_index().render()

Keep in mind the docs still claim these features are provisional and subject to change. More info here: https://pandas.pydata.org/pandas-docs/stable/style.html#Hiding-the-Index-or-Columns.
