代码以找到excel列中连续非空单元格的总和，直到出现空单元格？

Question

In B1 I want to sum all the cells of first column till the empty cell occurs.

Answer 1

Use this:

=SUM(A1:INDEX(A:A,MATCH(1E+99,A:A)))

The INDEX/MATCH formula finds the last cell that has a numeric value and sets that as the end of the Range in the SUM() formula.

But ultimately if you want to sum every number in Column A then a simple Sum of the whole column will work:

=SUM(A:A)

The SUM() Function ignores text and blank cells.

If what is wanted is to sum till the first blank cell and there is data after that then use this instead:

=SUM(A1:INDEX(A:A,MATCH(TRUE,INDEX(A:A="",0),0)))
