How to preserve additional column of pandas dataframe in pivot table

I have created pandas data frame on which I have applied pivot_table(). After applying pivot_table() the additional columns which are not mentioned in Index and column parameter. when result data frame is generated additional columns are lost. I need to preserve those columns.

Here is the code:

columns in pandas dataframe
df = [CustomerId, CustomerName,CustomerEmail, RateId, RateValue,Label1,Rate1,Label2,Rate2]

df_Pivot = pd.pivot_table(df, values=['Rate1,‘Rate2’], index =[‘CustomerId’,‘RateId’], columns=[‘Label1’,‘Label2’], aggfunc=np.sum, fill_value=0)

In the resulting data frame df_Pivot below columns are lost:

[CustomerName,CustomerEmail,RateValue]

I want to preserve additional columns in resulting data frame.
