Looks like the data is not formatted correctly ..

This is how your data object assigned to the table should look like:

let cars = [
   {"brand": "VW", "year": 2012, "color": "Orange", "vin": "dsad231ff"},
   {"brand": "Audi", "year": 2011, "color": "Black", "vin": "gwregre345"},
   {"brand": "Renault", "year": 2005, "color": "Gray", "vin": "h354htr"},
   {"brand": "BMW", "year": 2003, "color": "Blue", "vin": "j6w54qgh"},
   {"brand": "Mercedes", "year": 1995, "color": "Orange", "vin": "hrtwy34"},
   {"brand": "Volvo", "year": 2005, "color": "Black", "vin": "jejtyj"},
   {"brand": "Honda", "year": 2012, "color": "Yellow", "vin": "g43gr"},
   {"brand": "Jaguar", "year": 2013, "color": "Orange", "vin": "greg34"},
   {"brand": "Ford", "year": 2000, "color": "Black", "vin": "h54hw5"},
   {"brand": "Fiat", "year": 2013, "color": "Red", "vin": "245t2s"}
