javascript - 初学者 : Setting up React Gantt chart using google charts

Question

目标:在React中显示甘特图。目前正在使用 Google Charts 和来自 github 的 React 包装器。我对 React 和 JS 还很陌生，我正在努力学习!

问题:可能误解了一些我尚未意识到的关键问题!我找不到帮助我克服这个困难的文档/示例。我 90% 确信我的语法是错误的，但几个小时后我仍然认为我没有走在正确的轨道上。

我正在使用的资源:

React google charts Gant example尝试使用 Prop 窗口作为指导

^ The github readme from the above, specifically using the rows/columns setup

This older SO question.

当前停留在渲染上的代码:

import { Chart } from 'react-google-charts';
import React from 'react';

class ExampleChart extends React.Component {
  constructor(props) {
    super(props);
    this.state = {

      rows: [
        ['Research','Find sources','2015-01-01T08:00:00.000Z','2015-01-05T08:00:00.000Z',null,100,null],
        ['Write','Write paper',null,'2015-01-09T08:00:00.000Z',259200000,25,'Research,Outline'],
        ['Cite','Create bibliography',null,'2015-01-07T08:00:00.000Z',86400000,20,'Research'],
        ['Complete','Hand in paper',null,'2015-01-10T08:00:00.000Z',86400000,0,'Cite,Write'],
        ['Outline','Outline paper',null,'2015-01-06T08:00:00.000Z',86400000,100,'Research'],
      ],

      columns: [
        {
          id:'Task ID',
          type:'string',
        },
        {
          id:'Task Name',
          type:'string',
        },
        {
          id:'Start Date',
          type:'date',
        },
        {
          id:'End Date',
          type:'date',
        },
        {
          id:'Duration',
          type:'number',
        },
        {
          id:'Percent Complete',
          type:'number',
        },
        {
          id:'Dependencies',
          type:'string',
        },
      ],
    };
  }


  render() {
    return (
      <Chart
             graph_id="ganttchart"
             chartType = "Gantt"
             columns={this.state.columns}
             rows={this.state.rows}
             chartPackages={['gantt']}
             width="100%" height="9999px">
         </Chart>
    );
  }
}
export default ExampleChart;

react-google-charts 似乎需要 Date 对象。我没有在源代码中明确验证这一点，但是当我将 rows 更改为:

时，一切都呈现正常

rows: [
    ['Research','Find sources',new Date(2015,1,1,8,0,0), new Date(2015,1,5,8,0,0),null,100,null],
    ['Write','Write paper',null,new Date(2015,1,9,12,0,0),259200000,25,'Research,Outline'],
    ['Cite','Create bibliography',null,new Date(2015,1,7,8,0,0),86400000,20,'Research'],
    ['Complete','Hand in paper',null,new Date(2015,1,10,8,0,0),86400000,0,'Cite,Write'],
    ['Outline','Outline paper',null,new Date(2015,1,6,8,0,0),86400000,100,'Research'],
],
