One way is to use dynamic sql.
Assuming data type int for all columns, you can do something like this:

Create and populate sample table (Please save us this step in your future questions):

DECLARE @T table
(
    col char(1)
)

INSERT INTO @T VALUES ('a'), ('b'), ('c')

Build the dynamic sql:

DECLARE @Sql nvarchar(max) = 'CREATE TABLE YourNewTableName ('

SELECT @Sql = @Sql + col +' int,'
FROM @T 


SET @Sql = LEFT(@Sql, LEN(@Sql) - 1) +');'
--Print @sql

Execute it (You will probably want to print it before to make sure it's correct):

EXEC(@Sql)
