User assigned with Custom Security role unable to add columns in the table which is created in Default Environment.
We have created table in Power Apps under Default Environment
We have created the New security role, didn't copy from existing role.
Assigned required permission (Full permission) under Custom table to the respective table.
Assigned the custom security role to user.
User able to see the table under Default environment
User able add rows to the table, but unable to Edit/Add/Delete columns to the table.
There is no any lock symbol to the column.
