Updating only ONE cell using updateRecord?

Hi, can I update only ONE cell from my datable? Or do I need to pass the entire object ?

Datatable columns
ID
NAME
AGE

{id:1, name: “Caroline”, age: 12},
{id: 2, name: “Harry”, age: 20}

The following sets the AGE column of the ID=1 to undefined?

==>

{id:1, name: “Peter”, age: undefined}
{id: 2, name: “Harry”, age: 20}

updateRecord(“Test”, {id:1, NAME: “Peter”}, function(record, success) {

});

Thanks.

Here is the documentation for the updateRecord method. If this does not help, please share a link to your code.
