问如何使用React JS将FusionTablesLayer放入Google Maps API？

EN

import React from 'react';
import loadGoogleMapsAPI from 'load-google-maps-API';

const MAP_STYLES = {
    height: '450px',
    width: '100%'

}

const OPTIONS = {
    center: {
        lat: 41.850033,
        lng: -87.6500523
    },
    zoom: 13,

}

const API_CONFIG = {
    key:'My_Key xxxxxxx',
    language: 'en'
}

export default class InitialMap extends React.Component{
    componentWillUnmount() {

        const allScripts = document.getElementsByTagName( 'script' );

        [].filter.call(
            allScripts,
            ( scpt ) => scpt.src.indexOf( 'My_Key xxxxxxx' ) >= 0
        )[ 0 ].remove();

        window.google = {};


    }

    componentDidMount() {

        loadGoogleMapsAPI( API_CONFIG ).then( googleMaps => {
            new googleMaps.Map( this.refs.map, OPTIONS  );
        }).catch( err => {
            console.warning( 'Something went wrong loading the map', err );
        });

    }

    render() {
        return (
            <div id="page-wrapper">
                <div id= "page-header">
                    <div ref="map" style={MAP_STYLES}>

                    </div>
                </div>
            </div>
        )
    }
}

    function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    center: {lat: 41.850033, lng: -87.6500523},
    zoom: 11
  });

  var layer = new google.maps.FusionTablesLayer({
    query: {
      select: '\'Geocodable address\'',
      from: '1mZ53Z70NsChnBMm-qEYmSDOvLXgrreLTkQUvvg'
    }
  });
  layer.setMap(map);
}
