（1）：修改 src/index.js

         關鍵代碼：

        // 2. Plugins         app.use(createLoading());

import dva from 'dva';
import { browserHistory } from 'dva/router';
import createLoading from 'dva-loading';
import { message } from 'antd';
import './index.html';
import './index.css';

const ERROR_MSG_DURATION = 3; // 3 秒

// 1. Initialize
const app = dva({
  history: browserHistory,
  onError(e) {
    message.error(e.message, ERROR_MSG_DURATION);
  },
});

// 2. Plugins 
app.use(createLoading());

// 3. Model
app.model(require('./models/users'));

// 4. Router
app.router(require('./router'));

// 5. Start
app.start('#root');

（2）: 修改component  如: components\Users\Users.js

A: 傳入參數 loading    

function Users({ dispatch, list: dataSource, loading, total, page: current }) 

B: loading 放入 table

        <Table
          columns={columns}
          dataSource={dataSource}
          loading={loading}
          rowKey={record => record.id}
          pagination={false}
        />

C: model 放入 loading state裏面

        <Table
          columns={columns}
          dataSource={dataSource}
          loading={loading}
          rowKey={record => record.id}
          pagination={false}
        />

import React from 'react';
import { connect } from 'dva';
import { Table, Pagination, Popconfirm, Button } from 'antd';
import { routerRedux } from 'dva/router';
import styles from './Users.css';
import { PAGE_SIZE } from '../../constants';
import UserModal from './UserModal';

function Users({ dispatch, list: dataSource, loading, total, page: current }) {
  function deleteHandler(id) {
    dispatch({
      type: 'users/remove',
      payload: id,
    });
  }

  function pageChangeHandler(page) {
    dispatch(routerRedux.push({
      pathname: '/users',
      query: { page },
    }));
  }

  function editHandler(id, values) {
    dispatch({
      type: 'users/patch',
      payload: { id, values },
    });
  }

  function createHandler(values) {
    dispatch({
      type: 'users/create',
      payload: values,
    });
  }

  const columns = [
    {
      title: 'Name',
      dataIndex: 'name',
      key: 'name',
      render: text => <a href="">{text}</a>,
    },
    {
      title: 'Email',
      dataIndex: 'email',
      key: 'email',
    },
    {
      title: 'Website',
      dataIndex: 'website',
      key: 'website',
    },
    {
      title: 'Operation',
      key: 'operation',
      render: (text, record) => (
        <span className={styles.operation}>
          <UserModal record={record} onOk={editHandler.bind(null, record.id)}>
            <a>Edit</a>
          </UserModal>
          <Popconfirm title="Confirm to delete?" onConfirm={deleteHandler.bind(null, record.id)}>
            <a href="">Delete</a>
          </Popconfirm>
        </span>
      ),
    },
  ];

  return (
    <div className={styles.normal}>
      <div>
        <div className={styles.create}>
          <UserModal record={{}} onOk={createHandler}>
            <Button type="primary">Create User</Button>
          </UserModal>
        </div>
        <Table
          columns={columns}
          dataSource={dataSource}
          loading={loading}
          rowKey={record => record.id}
          pagination={false}
        />
        <Pagination
          className="ant-table-pagination"
          total={total}
          current={current}
          pageSize={PAGE_SIZE}
          onChange={pageChangeHandler}
        />
      </div>
    </div>
  );
}

function mapStateToProps(state) {
  const { list, total, page } = state.users;
  return {
    loading: state.loading.models.users,
    list,
    total,
    page,
  };
}

export default connect(mapStateToProps)(Users);
