Expand / Collapse Rows in Spreadsheet

I'd like to be able to collapse rows of categorized data so that I can more easily see all of the categories, with the ability to expand them to see individual rows.

When I search, I find this demo, but with no explanation of how to make it

For example, this list

Item	Style	Qty	Price	Total
Apple	Green	4	0.49	1.96
Apple	Red	9	0.35	3.15
Apple	Yellow	7	0.49	3.43
Grape	Red	100	0.05	5.00
Grape	Green	150	0.04	6.00
*Total*		*270*		*19.54*

Could instead be this:

Item	Style	Qty	Price	Total
► Apples		20		8.54
► Grape		250		11.00
*Total*		*270*		*19.54*

With the ability to expand like this:

Item	Style	Qty	Price	Total
▼ Apples		20		8.54
Apple	Green	4	0.49	1.96
Apple	Red	9	0.35	3.15
Apple	Yellow	7	0.49	3.43
▼ Grapes		250		11.00
Grape	Red	100	0.05	5.00
Grape	Green	150	0.04	6.00
*Total*		*270*		*19.54*

This is for collaborating with our supplier. We order multiple sizes of one thing, with about 10 different things altogether, so this would help a lot in making it easier for both of us to have an overview of the order.
