title: How do I update vuetify data table component with new data and new columns
body: <p>I am wondering how I take an existing (initial) v-data-table component whose :headers and :items props are populated, and then completely re-render the component with new data and new column headers? Is there a special update or destroy native Vue or Vuetify way to do this?</p>
  <p>I want my UX to be: See initial table that is created on mount, choose new columns, click update, queue loader icon, table is re-rendered with new items and new headers.</p>
  <p>Thanks in advance.</p>
