el: "#table",
data() {
return {
items: [
{ firstname: "John", lastname: "Doe", cars: ["Ferrari", "Tesla"] },
{ firstname: "Jane", lastname: "Doe", cars: ["BMW", "Civic"] },

{ key: "lastname", label: "Last name" },
{ key: "cars", label: "Cars" }

};
},
methods: {
join() {
for (let item of this.items) {
item.cars = item.cars.join("

}
}
}
});
