It seems like the sorting functionality is not working properly due to mismatching header ids and properties in the array of objects fetched from the backend.
I've realized that I need to create a custom sortingDataAccessor function, but I'm unsure about how to go about implementing it. Any guidance on this matter would be greatly appreciated!
