You can also enable a summary row in via Table add ons and configure default options for each column by clicking the add on editor. End users will be able to toggle desired aggregations from the summary row component itself.
Fantastic! I have two clients that will really like this.
I am playing around with how to implement this for one of them.
When you have more than one group level, it would be super nice to show the count of how many unique items are in the lower level.
I have an imperfect hack. The grouping is on Type and Town text fields. Each Type and Town also has a id and I use unique count on the town id column and call it Town Count. The issue is the Town Count column always shows 1 when it is visible. Makes sense as there is on one of each town. The individual record shows the actual id value. Confusing. Is there a better way?
Not sure if this has been split off into another topic, but there are some oddities and some feature requests in the aggregation functionality that would be nice to resolve:
Issue: When aggregating by Average, NULL values are interpreted as 0. While possibly valid if a user intends NULL to be interpreted as 0, but usually NULL is meant to be NULL and calculation of average should ignore these records.
In other words, average(2, 3, 0, 7) = 12 / 4 = 3 while average(2, 3, NULL and 7) = 12 / 3 = 4.
Perhaps a switch to allow both options, but if not, defaulting to NULL being not counted as an observation instead of NULL = 0 is more appropriate.
It would be useful to add FIRST_VALUE and LAST_VALUE to the default aggregations. This is especially useful for time series (i.e. when grouped, show the final result of a running total column). MIN/MAX doesn't always work here as a field could be declining or increasing over time and therefore the final value might be either the MIN or MAX (or, frankly, none of the above).
I don't have a specific use case for it, but having the ability to aggregate by MODE may also be useful
I'd really like to enable/disable aggregations by level of grouping. For example, it may make sense to sum a field for the lowest level of grouping, but not across the top level of grouping. If I could hide the aggregation at the top level and leave it on for the lower level when expanded, that would be great.
I would also like to have a concatenation (CONCAT) summation (tricky I'm sure). But I'm often wanting to summarise text fields, and first/last is okay but sometimes, if it's just a few characters, or just a few entries, it would be nice to have them concatenated?

Hey! Would it be possible to for the cell tooltip to show info from another column? For example, if you hover over a cell in the 'User' column, the data in from the relative 'Bio' cell is in the tooltip.
