fix n_total after create_table_group_x_variable

[RedEggplant1]

Coucou :)

I use create_table_group_x_variable by specifying value_columns =c("stat", "n_total"), because that's how I want to present the output: with n_total for each question.

The problem is that when you do that, if for a certain disaggregation no respondent selected the response option, the value is NA (which is normal), but n_total is NA. Instead, n_total should be equal to the n_total of this disaggregation that answered to that question, even if that specific response option is not selected.

Second, nice to have, if there was a possibility when we chose to show n_total to only keep one column n_total per question, and it being located after all % for that question, it would be really smooth (for now there is one n_total per response option). I m coding some tiny stuff on my side so that it is done that way but it s always nice to mainstream this.
