Ant Design中Spin组件使用（以表格加载为例）

import React, { Component } from 'react'
import { Table, Spin } from 'antd';
import axios from 'axios'

export default class Home extends Component {
    state = {
        selectedRowKeys: [], // 表格选择项Keys
        selectedRows: [], // 表格选择项Rows
        tableData: [],
        total: 0,
        tableLoading: false // 加载状态
    }

    getColumns = () => {
        return [
            {
                title: 'ID',
                dataIndex: 'id',
                width: 30,
            },
            {
                title: '标题',
                dataIndex: 'title',
                width: 500,
                render: (text, record) =>  this.handleShowDetailBlog(record.id)}>{text}
            },
            {
                title: '内容',
                dataIndex: 'content',
                render(text, record) {

            },
            {

                dataIndex: 'datetime'
            }
        ];
    }
