Is there a way tableone can provide row totals?

[fralickm]

Huge fan of tableone. This is my first time posting on github. Is there a way for tableone to take a continuous variable and calculate its total rather than its mean?

For example I have a dataset where rows are different pharmacies and one column is units sold of a drug. I want tableone to show the total units sold across all pharmacies rather than showing the mean number of units sold at each pharmacy.
