Free space not used.

Executing
exec sp_spaceused <my_table>
I notice this:
reserved --> 4483504 KB
data --> 2536720 KB
unused --> 1896984 KB
I have to "free" that space and I tried the following:
1) DBCC DBREINDEX (<my_table> )
2) DBCC SHRINKDATABASE ('<my_db>')
but the didn't work.
How can I do to "give" that space to Os?
Any help much appreciated.
Best regards.
