i want to change the add or remove on the invoices quotation atc templates
If you have questions, be specific. What do you mean by “change the add or remove?” There is no “add” or “remove” to change.
I meant add Column or delete it in the templates
You can’t do that. Any column applicable to the form that has content will show. Any column with no content will not. What column are you trying to delete or add?
