Applying a React component button with React CustomRenderer

This is an example of applying a React component button (switch) with CustomRenderer in React.

//app.js
import './App.css'
import { GridView, LocalDataProvider } from 'realgrid'
import { columns, fields, rows } from './realgrid-data'
import { useEffect, useRef } from 'react'
import { createRoot } from 'react-dom/client';

               <span className="slider round"></span>
           </label>
