How to create trigger on table to audit details newly added records

CREATE TABLE [dbo].[T1](
 [id] [int] IDENTITY(1,1) NOT NULL,
 [name] [varchar](50) NULL,
 [address] [varchar](500) NOT NULL,
 [companyname] [varchar](100) NOT NULL
) ON [PRIMARY]

CREATE TABLE [dbo].[T2](
 [Id] [int] IDENTITY(1,1) NOT NULL,
 [type] [varchar](50) NULL
) ON [PRIMARY]

Now i want to enter for each insert, update, delete operation on T1.
so craete trigger on T1.

CREATE TRIGGER [dbo].[TriT1] on [dbo].[T1] for insert, update, delete
as
 
declare @insRecord int,@Type char(8) ,@delRecord int
BEGIN
 SET NOCOUNT ON;
select * into #ins from inserted
 select * into #del from deleted
select @insRecord = count(1) from #ins
 select @delRecord = count(1) from #del
if @insRecord > 0 
  if @delRecord > 0
   select @Type = 'Update'
  else
   select @Type = 'Create'
 else  
  select @Type = 'Delete'
    -- Insert statements for trigger here
    if @insRecord >0 or @delRecord >0 
    begin
    insert into T2 values (@Type )
       end    
END
GO
