 'react-admin';
const CustomEmpty = () => <div>No books found</div>;
const DatagridEmpty = () => (
    <List resource="t_geyao_person">
        <Datagrid empty={<CustomEmpty />}>
        <TextField source="id" />
            <TextField source='name'></TextField>
            <TextField source='sex'></TextField>
            <TextField source='salary'></TextField>
            <BooleanField source='status'></BooleanField>
        </Datagrid>
    </List>
