Have a look at DBCC showfilestats or sp_spaceused for filegroups.
Found a script at a blog. That lists tables and their sizes. For a more user friendly (administrative view, you can generate reports using right mouse on the db).
This will show you all kinds of goodness:
-- Script to analyze table space usage using the
-- output from the sp_spaceused stored procedure
-- Works with SQL 7.0, 2000, and 2005

Found a solution.
It seems like it takes longer to type this out than using UI to find out table FILEGROUP information.
Found through List tables in filegroups:
declare @objectid bigint
set @objectid = object_id('table_name')
exec sp_objectfilegroup @objectid
I became too lazy to type those three lines so ended up creating another stored procedure that takes table name instead.
create procedure spTableFileGroup
@TableName sysname
as
begin
if exists( select 1
from INFORMATION_SCHEMA.TABLES T
where T.TABLE_NAME = @TableName) begin
declare @objectid bigint
set @objectid = object_id(@TableName)
exec sp_objectfilegroup @objectid
end
else begin
print 'There is no table named "' + @TableName + '"'
end
end
GO
Usage
exec spTableFileGroup 'table_name'
GO
The tables FILEGROUP is determined by it's clustered index. You can use this query to find the filegroup:
SELECT *
FROM
sys.tables AS tbl
INNER JOIN sys.indexes AS idx ON idx.object_id = tbl.object_id and idx.index_id < 2
LEFT OUTER JOIN sys.data_spaces AS dsidx ON dsidx.data_space_id = idx.data_space_id
In regard to your second question, I don't think there's any documentation, however, you can use SQL profiler when you view the details in SSMS. This will show you the exact queries.
The system stored procedure sp_help could be a good starting point.
For example:
exec sp_help 'schema.TableName'
