Users should be able to access the in memory tables from the SQL Server agent | Databases | In Memory | Select a database name | Tables and Indexes tab
The collection itself gets the resource pool name, total allocated indexes, total allocated system, total allocated tables, pool consumption percentage, total used tables, total used indexes, and total used system for the instance by database.
The table data collection provides same data used from the databases panel (table_mb, reserved memory, used memory mb, rows, percent of db, etc). It is not specific to in-memory.
