 **Tip**: If you want to override the `header` and `cell` styles independently for each column, use the `headerClassName` and `cellClassName` props in `<Field>` components. For instance, to hide a certain column on small screens:
 
 ```jsx
-import { withStyles } from '@material-ui/core/styles';
+import { makeStyles } from '@material-ui/core';
 
-const styles = theme => ({
+const useStyles = makeStyles(theme => ({
     hiddenOnSmallScreens: {

             display: 'none',
         },
     },
-});
+}));
 
-const PostList = ({ classes, ...props }) => (
-    <List {...props}>
-        <Datagrid>
-            <TextField source="id" />

-            />
-        </Datagrid>

-);
+const PostList = props => {
