How to add space between rows and sum up automatically in Excel - excel

Question

let's say that I have a table like the below:
| | Value 1 | Value 2 | Value 3 | |
|---|---------|---------|---------|---|
| A | 22 | 12 | 3 | |
| A | 5 | 6 | 12 | |
| A | 19 | 9 | 13 | |
| A | 22 | 43 | 31 | |
| B | 7 | 12 | 23 | |
| B | 5 | 5 | 8 | |
| B | 35 | 78 | 9 | |
| B | 45 | 1 | 8 | |
| C | 34 | 56 | 0 | |
| C | 22 | 1 | 14 | |
| C | 13 | 46 | 45 | |
and that I'd need to transform it into the below:
| | Value 1 | Value 2 | Value 3 | |
|---|---------|---------|---------|---|
| A | 22 | 12 | 3 | |
| A | 5 | 6 | 12 | |
| A | 19 | 9 | 13 | |
| A | 22 | 43 | 31 | |
| | 68 | 70 | 59 | |
| | | | | |
| B | 7 | 12 | 23 | |
| B | 5 | 5 | 8 | |
| B | 35 | 78 | 9 | |
| B | 45 | 1 | 8 | |
| | 92 | 96 | 48 | |
| | | | | |
| C | 34 | 56 | 0 | |
| C | 22 | 1 | 14 | |
| C | 13 | 46 | 45 | |
| | 69 | 103 | 59 | |
How could I obtain the desired effect automatically?
There would be n empty rows after each group and the sums of each column within the group.

Answer 1

You can use the Subtotal feature of Excel. Subtotal is in the "Data" tab of the ribbon. To automatically add the totals between groupings. I don't think it adds the blank row. If you absolutely need the blank row, then I can generate some VBA that will work.
