> Create contingency table for two columns in a DataFrame. This is `table` in R
> and `crosstab` in pandas.
> ~~~
> df.stat.crosstab(col1, col2): DataFrame
> ~~~
> It returns a local DataFrame with "$col1_$col2" and values from col2 as the
> column names. Values from col1 become the values in the first column.
> If users want to ignore NA, they should filter NAs first.
