df.style des not render pivot tables in the same fashion as to_html
Please see 
http://stackoverflow.com/questions/37166730/how-do-i-preserve-hierarchical-tables-with-pandas-pivot-table-and-dataframe-styl
#### Code Sample, a copy-pastable example if possible

```
import pandas as pd
import numpy as np

np.random.seed(0)
a = np.random.randint(1, 4, 10)
b = np.random.randint(1, 4, 10)
c = np.random.randint(5, 9, 10)

df = pd.DataFrame(dict(A=a,B=b,C=c,Val=np.random.randint(1,10,10)))

tbl=pd.pivot_table(df,index=['A','B','C'], aggfunc=sum)
print tbl.to_html()
print tbl.style.render()
```
#### Expected Output

Expect that both tables will produce nearly indentical hierarchically structured tables, and in particular, the second table will not have every index value repeated.
