Add Column whit row SUM for dynamic columns

Massimo74

Hi, I used the Movil function for dynamic columns, thanks Movil works great !!!
https://github.com/martinberlin/datatables-dynamic-columns

now I would like to add a last column that makes me the sum of the row, I remind you that I don't know how many columns there will be and not even the name of them the only thing I know that I can position it as column n ° 5
you have an example of how to add the column and put the sum of the row ???
Thanks
