title: React-admin framework, how to style the datagrid?
body: <p>I read the documentation and I can't seem to style the datagrid 100% freely... I can only change small things, or am I wrong? Let's say I want to use the datagrid features, but I want to leave 100% of the styling to my discretion, is that possible?</p>
  <p>The code below was the little I managed to style, but it's not enough:</p>
  <pre><code>const useStyles = makeStyles({
    table: {
      backgroundColor: '#1C00ff00',
      borderBottom: 'none',
      fontFamily:'Noto Sans Mono'
    },
    headerCell: {
      backgroundColor: 'MistyRose',
      border:'none',
      boxShadow:&quot;none&quot;
    },
    row: {
      color: '#fff',
      border:'none',
      backgroundColor:&quot;#FFFFFF 0% 0% no-repeat padding-box&quot;,
      boxShadow:&quot;0px 0px 6px #000000&quot;,
      opacity:&quot;0.7&quot;,
      borderRadius:&quot;5px&quot;,
    },
    coluna1: {
      width: '10%'
    },
    coluna2: {
      width: '35%'
    },
    coluna3: {
      width: '35%'
    },
  });
  
  </code></pre>
