Is it possible to get a nicely formatted table from a pandas dataframe in ipython notebook when using nbconvert to latex & PDF?

There is a simpler approach that is discussed in this Github issue. Basically, you have to add a _repr_latex_ method to the DataFrame class, a procedure that is documented from pandas in their official documentation.

I did this in a notebook like this:

import pandas as pd

pd.set_option('display.notebook_repr_html', True)

def _repr_latex_(self):
    return "\centering{%s}" % self.to_latex()

pd.DataFrame._repr_latex_ = _repr_latex_  # monkey patch pandas DataFrame

The following code:

d = {'one' : [1., 2., 3., 4.],
     'two' : [4., 3., 2., 1.]}
df = pd.DataFrame(d)
df

turns into an HTML table if evaluated live in the notebook, and it converts into a (centered) table in PDF format:

$ ipython nbconvert --to latex --post PDF notebook.ipynb
