      this.state = {
        checked: false,
        rows:[],
        json: []
      }
    }

    componentDidMount() {
      this.setState((prevState) => {
        return {
          json: getJson(),
        }
      })
    }

    checkboxHandler() {

      }

    render() {
      return (
        <div>
          <table>
            <tbody>
              {this.state.json.map((obj, i) => {
                return (
                  <tr key={obj.id}>
                    {obj.items.map((data, i) => {
                        return( 
                            <td key={data.id}> 
                                <p>{data.label}</p>
                                    <input 
                                        type="checkbox" 
                                        checked={data.value}
                                        onChange={this.checkboxHandler} 
                                    />
                            </td>
                        )
                    })}
                  </tr>
                )
              })}
            </tbody>
          </table>
        </div>
      )
    }
  }

  export default TableComponent;
