title: How can I change remove the filter icon when using the material-table library?
body: <p>I would like to remove the filter icons and just have blank input boxes.  I have tried using the column prop <a href="https://material-table.com/#/docs/all-props" rel="nofollow noreferrer">filterCellStyle</a> but the icon can't be reached since it's inline styling.</p>
  
  <pre><code>
  import React, { Children } from "react";
  import ReactDOM from "react-dom";
  import MaterialTable  from 'material-table';
  
  class Example extends React.Component {
    render() {
      return (
        &lt;MaterialTable
          title="Non Filtering Field Preview"
          columns={[
            { title: 'Name', field: 'name', filterCellStyle: {
              background: "red"
            }},
  
            { title: 'Surname', field: 'surname' },
            { title: 'Birth Year', field: 'birthYear', type: 'numeric' },
            {
              title: 'Birth Place',
              field: 'birthCity',
              lookup: { 34: 'İstanbul', 63: 'Şanlıurfa' },
            },
          ]}
          data={[
            { name: 'Mehmet', surname: 'Baran', birthYear: 1987, birthCity: 63 },
            { name: 'Zerya Betül', surname: 'Baran', birthYear: 2017, birthCity: 34 },
          ]}        
          options={{
            filtering: true
          }}
  
        /&gt;
      )
    }
  }
  
  const rootElement = document.getElementById("root");
  ReactDOM.render(&lt;Example /&gt;, rootElement);
  </code></pre>
