title: MUI datatable, Hide search Icon but still show the search bar
body: <p>Im working with MUI-datatable and my table options contain</p>
  <pre><code>options:{
  search: false,
  searchOpen: true,
  ...
  }
  </code></pre>
  <p>according to the docs &quot;search:false&quot; should only hide the icon to toggle the search bar, and searchOpen, should show the search bar by default.</p>
  <p>But at the moment it removes the search bar AND icon.</p>
  <p>Here is a sandbox where I have search set to disabled which only disables the icon (but actually want to set to false)</p>
