You can use dynamic SQL

DECLARE @TableNo1 TABLE(Field varchar(128),DataType varchar(128))
DECLARE @s nvarchar(max)='CREATE TABLE dbo.TableNo2('
INSERT INTO @TableNo1
VALUES
('Field1','nvarchar(max)'),
('Field2','int')

SELECT  @s+=T.Field+' '+T.DataType+',' FROM   @TableNo1 T
SET @s=LEFT(@s,LEN(@s)-1)+')'
EXECUTE(@s)
