Como deixar simbolo de valor monetario somente nas celulas de valor total?

Hello, 
 
Thank you for writing to us. 
 
If we understand correctly, you would like to show a currency symbol only in the total cells.
If this is the case, we kindly suggest using the customizeCell hook.
We have prepared a JSFiddle example for illustration: https://jsfiddle.net/flexmonster/cwkxhpnd/.
 
Please let us know if this is what you are looking for.
Looking forward to your feedback.
 
Kind regards, 
Vera
