SQL Server 2008 :: Parent Records Ordering And Display Child Records Next To It?

declare @table table (
ParentID INT,
ChildID INT,
Value float
)
INSERT INTO @table
SELECT 1,1,1.2

[code]....

This case ParentID - Child 1 ,1 & 2,2 and 3,3 records are called as parent where as null , 1 is child whoose parent is 1 similarly null,2 records are child whoose parent is 2 , .....

Now my requirement is to display parent records with value ascending and display next child records to the corresponding parent and parent records are sorted ascending

--Final output should be

PatentID ChildID VALUE
33 1.12
null3 56.7
null3 43.6
11 1.2
null1 4.8
null1 4.6
22 1.8
