title: Is it possible to create a multi-line header in a Vuetify datatable?
body: <p>I would like to create a table with a multiline header, like in <a href="https://i.stack.imgur.com/ShrCz.png" rel="nofollow noreferrer">this example</a>. </p>
  
  <p>I've found <a href="https://stackoverflow.com/questions/53027979/vuetifyjs-how-to-create-multi-lines-header-in-v-data-table">this post</a>, however the answer does not work. Furthermore, I have looked at the Vuetify documentation and Github issues, but there seems to be no solution. </p>
  
  <p>Would be great if someone could let me know whether something like this is possible and if so how.</p>
