Calc question

Dang, I hate the new list behavior of replying to the sender instead of the list. Can't that be changed back? My reply below, sent only to Alan B by mistake.

What's a pivot table? Pointers to introductory tutorials will be
appreciated.

Thanks.

Hi,
for Pivot Table try to read this chapter: https://wiki.documentfoundation.org/images/6/69/CG4108-PivotTables.pdf

You might have a look at this video here:

No association with the user. Note that he uses the term Data Pilot instead of Pivot Table, but they are essentially the same thing. Earlier versions of LibreOffice used Data Pilot as the term for Pivot Table.

alternatives suggested to OP

Now from computer instead of phone

Yes pivot table can do that. I've used it many times. Have you tried the
Subtotal method I described?

Has anybody tried both Carl's method and mine?

It would be interesting if there's a consensus given OP's expectation of
unskilled users and intended outputs? Anybody?

After using both myself, and the pivot table MUCH more than the Subtotal
option I favor the Subtotals. Fewer clicks to get result, result displays
by adding rows to existing data no need to look somewhere else (another
tab) , using outline button can display rows of only customer name and
total purchase, then with outline and row expansion show purchase detail
for individual customer, once Subtotal has been applied totals and customer
detail can be displayed or hidden with one click, no need to open a menu,
it seemed users may be familiar with sort and up to clicking the "OK"
button on the Subtotal dialog this seems to me more similar to sort.
Other ideas?
