How to add a custom button at child table form


I am working on a feature that fetches a list of buttons that have to be added to a child table form.

I have this child table and I would like to add a custom button just like the remove, insert above… buttons

I found this discussion:

But this approach adds the button at the child table, not at a row

I hope you can help me, thank you!

Did you try adding a field (type : Button) in child table and enable in_list_view ?
