Exporting the data to CSV

One feature that we will also implement is a comma-separated values (CSV) export of the data. We don’t need any extra libraries for the export because the MUI data grid provides this feature. We will activate the data grid toolbar, which contains a lot of nice features:

1. Add the following import to the Carlist.tsx file. The GridToolbar component is a toolbar for the MUI data grid that contains nice functionalities, such as export:

   import { 
     DataGrid, 
     GridColDef, 
     GridCellParams,
     GridToolbar
   } from '@mui/x-data-grid';
   

2. We need to enable our toolbar, which contains the Export button and other buttons. To enable the toolbar in the MUI data grid, you have to use the slots prop and set the value to toolbar: GridToolbar. The slots prop can be used to override the data grid’s internal components:

   return(
     <>
       <AddCar />
       <DataGrid
         rows={cars}
         columns={columns...
