 ### Aggregates
 
-Oftentimes, when displaying numbers in the table, users would like to be able to see the results from aggregate calculations at the bottom of the table columns. The  `o-table` component has support for the mostly used aggregate functions (count,sum,avg,min,max).
+Often when displaying numbers in a table, users want to show summary results of aggregate calculations at the bottom of the table columns. The `o‑table` component supports commonly used aggregation functions (**count**, **sum**, **avg**, **min**, **max**) using `aggregate` input and also allows specifying a **custom aggregation function** using the `aggregate-function` input, which may return either a **synchronous number** or a **Promise<number>** (for asynchronous operations).

 If there is at least one grouping, the table automatically applies the *sum function* on those of type `currency`, `integer` and `real` and whose value will be displayed in the grouped row.
 If you want to exclude this function from being performed, you must add this column in the `excluded-aggregate-columns` attribute in `o-table-columns-grouping` component.

  By default, when you change the aggregate function in a column, it will change in all grouped rows of the same level, if you want to avoid this behavior you must add `change-aggregate-same-level="no"`.
