Unable To ALTER A Temporary Table In TSQL

Is it possible to ALTER a temporary table in TSQL (SQL2000)?

The following TSQL reports a syntax error at the ALTER TABLE line:

DECLARE @Test TABLE(
[Col1] [int] NOT NULL ,
[Col2] [int] NOT NULL
)
ALTER TABLE @Test
DROP COLUMN Col2

I was hoping this would work the same way as a normal table. For example:

CREATE TABLE [dbo].[Test] (
[Col1] [int] NOT NULL ,
[Col2] [int] NOT NULL
) ON [PRIMARY]
GO
ALTER TABLE Test
DROP COLUMN Col2

EXEC sp_help Test

DROP TABLE Test
