I am using https://github.com/Okipa/laravel-table/ package for datatable generation and I have theme templates under
themes/back/resources/views/vendor/laravel-table
but laravel-table is still rendering from resources/views/vendor/laravel-table
I just removed resources/views/vendor/laravel-table folder and it started working. I don't know if theme manager is supposed to work so but it resolves my problem.
