Calculate new column which is sum of previous value of column

[Yerlasdu95]

Hi Folks, could you please help
How to calculate new column, which will sum each number in column [hours] one by one.

For example: Hours: [1,2,3,3,4,4,,8,8,8]

Will be new column: [1,3,6,9,13,17,25,33,41]

which is

1 = 1

2 = 3 (1+2)

3=6 (1+2+3)

3 = 9 (1+2+3+3) and etc

@Yerlasdu95 

you can create an index column in PQ

then use DAX to create a column

Column = sumx(FILTER('Table','Table'[Index]<=EARLIER('Table'[Index])),'Table'[Hours])
