Google表格-相邻列中显示的每n行的总和

Question

I am making a spreadsheet to manage my spending on food at work. At the moment, I am getting the total of every week in the last column, but I would also like to total the spending for the month, something like this, but neater and so I can just drag down the rows instead of manually type it every 4 rows.

Thanks for the help!

Answer 1

This is easy to manage - its all a question of which cell(s) you choose to select and drag. Don't just click and drag the cell with the formula; select the three blank cells as well - then drag four cells down the column. This will give a formula in every fourth row.

The SUM formula calculates the costs for the first 4 week period. All Good.

Now, if you select this cell and simply drag it down, then every cell will get a copy of that formula. not good.

and then drag all four cells down the column, then only every fourth cell will have a formula and the preceding three cells will be blank.
