This is a dorky, but very useful to me, daily diet spreadsheet. So I have one table where the first column is the date and then the food or exercise item. The number of entries in a day varies. Like this:
Entries
4/25/17 | 19 | Elliptical | 0 | 0 | 0 | -120 | 20 | minute |
4/25/17 | 22 | Salmon | 0 | 24 | 48 | 464 | 8 | ounce |
Then there is a summary table for each day, tied to graphs on another page. Each cell for that day is tied to an entry on a graph on another page.
Summary
So in the above 19 is a sum of the carbs for all the entries for 4/25 in the first table. For 4/26 I just copy that cell for 4/25, change the range manually, then copy that across to the other 3 cells, which automagically reflect the new range even though they are summing different columns.
What I would love to do is this, but I don't think it's possible in Numbers.
For instance for cell B in the Summary Table
if (Summary Table: date in cell in column a) = (Entry Table: date in cell in column a) include (Entry Table: value in cell in column d) in SUM range.
I know I could include summary lines in the Entries table per day but I don't want the Entries table to have anything but the raw data.
-------------
I restarted Numbers, also created a new spreadsheet and tried it, in case my existing one was borked. Nope, when I double click a cell with or without a formula nothing happens. I may have to restart and see if that fixes it. Good to know it DOES work. Meanwhile Ctrl= for the win.
