title: Remove dropdown arrow on vuetify data table header?
body: <p>I am struggling to remove the dropdown arrow next to the column names 'Name', 'Datum', 'Creator'...
  The dropdown arrow gets rendered in an i-Tag, and if I edit the html via Chrome and add 'display: none' it gets removed...</p>

  <p>however I am unable to access the i tag or the class v-icon via css in the code. Probably because it is not created before the rendering process.</p>
  
  <p>Is there any other way to remove the dropdown arrow?</p>
  
  <p>Thanks in advance!</p>
  
  <p>Html of my table, called 'file-list':</p>
