Is there a way to run some function like a trigger when a table is created in the database in SQL SERVER 2008?

Yes, it's called a DDL trigger. The documentation for CREATE TRIGGER
has a sample for DROP_SYNONYM
(a very questionable choice for an example) but you'll want the CREATE_TABLE
event instead. A better starting point in understanding how they work is probably here:
http://msdn.microsoft.com/en-us/library/ms190989.aspx
If you have more specific details, e.g. what exactly do you want to pass to this function (I assume you mean procedure), or what does the procedure do, we can provide more useful and specific help.

Yes a DDL Trigger. For example, here is some code I written to prevent some tables from being modified:
PRINT N'Create DDL trigger to prevent changes to various tables'
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER NoEditCertainTables ON DATABASE
FOR DROP_TABLE, ALTER_TABLE, CREATE_TABLE
AS
SET CONCAT_NULL_YIELDS_NULL ON
DECLARE @AffectedTable varchar(255)
SELECT @AffectedTable = EVENTDATA().value('(/EVENT_INSTANCE/ObjectName)[1]','nvarchar(100)')
--This is the name of the table(s) you dont want messed with
IF (@AffectedTable IN ('Table1','Table2','Table3'))
BEGIN
ROLLBACK;
END
SET CONCAT_NULL_YIELDS_NULL OFF
GO
