Beta release: In beta release, the summarize option enables you to display the sum (SUM) or average (AVG) for column values containing only numeric data.
Sum-up overview

Sum-up (

The Sum-up type configuration defined in the macro's edit mode is saved as the default for each column and will automatically apply with each Confluence page refresh.
