reactjs - 材料表 - 如果没有数据显示消息

Question

我正在使用材料表https://material-table.com/#/docs/get-started。但是，如果没有返回数据，我似乎找不到任何有关显示默认消息的信息？

我想知道是否有人知道我会怎么做。下面是我创建的测试表（带有假数据）。现在，如果该数据为空，我想要一条消息显示表格数据将在何处显示“立即创建广告”，并带有一个按钮。

import React from 'react';
import { forwardRef } from 'react';
import MaterialTable from 'material-table';
import AddBox from '@material-ui/icons/AddBox';
import ArrowDownward from '@material-ui/icons/ArrowDownward';

import ChevronRight from '@material-ui/icons/ChevronRight';
import Clear from '@material-ui/icons/Clear';

export default function MaterialTableDemo() {

    const tableIcons = {
        Add: forwardRef((props, ref) => <AddBox {...props} ref={ref} />),

    const columns = {columns: [

你可以用一种更优雅的方式来实现这一点，通过使用这样的localization道具：

<MaterialTable
    localization={{
        body: {
            emptyDataSourceMessage: (
                <Button color="primary" className={classes.button}>
                    Create your ad now
                </Button>
            ),
        },
    }}
    {...otherProps}
/>;
