问题 Say for example, I wanted to SUM all the values from the current row until the provided count. See table below: For example: Category A, Row 1: 10+15+25 = 50 (because it adds Rows 1 to 3 due to Count) Category A, Row 2: 15+25+30+40 = 110 (because it adds Rows 2 to 5 due to count) Category A, Row 5: 40+60 = 100 (because it Adds Rows 5 and 6.
