WITH Numbered AS 
(
  SELECT 
    ROW_NUMBER() OVER (ORDER BY Description) as rn,
    (ROW_NUMBER() OVER (ORDER BY Description) - 1) % 3 as colid,
    (ROW_NUMBER() OVER (ORDER BY Description) - 1) / 3 as line,
    Description 
  FROM Table1
)
SELECT desc1.description as DESC1, desc2.description as DESC2, desc3.description as DESC3
FROM   (SELECT line, description FROM Numbered WHERE colid=0) as desc1
LEFT JOIN 
       (SELECT line, description FROM Numbered WHERE colid=1) as desc2
ON (desc1.line = desc2.line)
LEFT JOIN 
       (SELECT line, description FROM Numbered WHERE colid=2) as desc3
ON (desc2.line = desc3.line)
