Hi Edel,
Thanks for contacting
Syncfusion support.
By default, the EJ2 Grid
column only supports number, string, date, dateTime, and boolean type values, and
it does not support array types of values. Refer to the below documentation.
columnType: https://helpej2.syncfusion.com/angular/documentation/grid/columns/columns#column-types
We can show an array of values in the Grid column using
columnTemplate/valueAccessor features. But, this is used only for display
purposes. We cannot perform any Grid actions like Filtering, Sorting, CRUD,
column-spanning, Searching, Grouping, etc., on the array-type column. This is
the behavior of EJ2 Grid.

valueAccessor: https://helpej2.syncfusion.com/angular/documentation/grid/columns/columns#display-array-type-columns
