DECLARE @Table Table(Col INT)
INSERT INTO @Table
SELECT 1 UNION ALL
SELECT 2 UNION ALL
SELECT 3 UNION ALL
SELECT 4 UNION ALL
SELECT 5 UNION ALL
SELECT 6 UNION ALL
SELECT 7 UNION ALL
SELECT 8 UNION ALL
SELECT 9 UNION ALL
SELECT 10

;WITH CTE AS
(
SELECT
ROW_NUMBER() OVER(ORDER BY Col) AS Row,
Col
FROM
@Table
)
SELECT DISTINCT
C.Col,
SUM(C1.Col) AS Sum
FROM
CTE AS C
LEFT JOIN
CTE AS C1 ON C1.Row <= C.Row
GROUP BY C.Col
ORDER BY C.Col ASC

This is called a running total. There are many ways to do this.
