Question On Primary Key, Unique Index

Question: I have a test table like this


CREATE TABLE [dbo].[Test](
[name] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[addr] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
CONSTRAINT [PK_Test] PRIMARY KEY CLUSTERED
(
[name] ASC
)WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]


But when I tried to input my data like
'abc', '123 abc'
'abc ','123 abc'

SQL server won't recognize 'abc' and 'abc ' is a different value if the last character is a space. Is there a way to make it as a different value? I tried to drop the primary and input the data. When I ran a group by the name column, 'abc' show 2 instead of 1. Seems SQL server is trying to ignore the space at the end too.

I also noticed unique index have the same problem too. Please help.
