Hi:
As far I know, hide_name_column: true works only when your doctype has a title field rather than your id(name field). Try to set as “title” other field, and you will see your ID as last column.

After that you can use hide column option …
I think there are some “hardcoded” behavior …
Please, if you found other solution … let me know 
Hope this helps.
