There are a number of restore options in 2005, including complete, partial, file and page restores.
If the table resides in a particular file and/or filegroup, there are other files and filegroups defined for that database, then do a partial and/or file restore;
Otherwise, do a full restore of the database;
NOTE: The restored database should not overwrite your existing database.
Finally, copy the data from the restored table (using SSIS or some other process) to the working database.
