Datatable with excelFilter in mode "date".

I need to display amounts in the header of a table.

But I observe strange behavior of checkboxes in the date column (mode: “date”). The rest of the columns are working correctly.
If I remove the event “onAfterFilter” (use only the button “sum”), then everything works correctly.

How to fix this behavior to automatically recalculate the sums on changes in the filter conditions?

Use the standard built-in aggregation functions.
