moving a table to another filegroup in T-SQL

Hi
I want to move a table to another filegroup using T-SQL (alter table ...).
In BOL i do not find an example of this case. I trried something like
alter <table>
move to <filegroup>
but it does not work
Can somebody help me please. Thanks WaldoDoes the table currently have a clustered index?
Do you want the table to have a clustered index after you have moved it?

Easiest method is to re-create the clustered index in new file group. This
will move the table to the new file group automatically.
This means data will be moved to new file group once you move the clustered
Index
If the table already has a clustered index, you can use the CREATE INDEX
command's WITH DROP_EXISTING clause to recreate
the clustered index and move it to a particular filegroup. When a table has
a clustered index, the leaf level of the index and the data pages of the
table essentially become one and the same. The table must exist where the
clustered index exists, so if you create or recreate a clustered
index-placing the index on a particular filegroup-you're moving the table to
the new filegroup as well.
