基本上，我有一組動態(tài)表，這些表是根據(jù)傳遞的值顯示的。如果傳遞了一個空數(shù)組，它應(yīng)顯示“未找到數(shù)據(jù)”。在我的情況下，當(dāng)我向表發(fā)送數(shù)據(jù)時，所有表將首先顯示“未找到數(shù)據(jù)”，然后是實際的表內(nèi)容。我不確定是什么原因造成的。數(shù)據(jù)是異步加載的，它顯示沒有找到的數(shù)據(jù)，然后顯示實際內(nèi)容。我添加了 setInterval 來展示這種異步特性沙盒：https://codesandbox.io/s/react-table-row-table-ryiny?file=/src/index.js:0-1322有人可以幫助我嗎？父母import * as React from "react";import { render } from "react-dom";import DataGrid from "./DataGrid";const d1 = [{ name: "test", age: "20" }, { name: "test1", age: "15" }];const d2 = [{ area: "area", pin: "123" }, { area: "area1", pin: "1245" }];const c1 = [  { Header: "Name", accessor: "name" },  { Header: "Age", accessor: "age" }];const c2 = [  { Header: "Area", accessor: "area" },  { Header: "Pin", accessor: "pin" }];const d3 = [];const c3 = [];class App extends React.Component {  constructor(props) {    super(props);    this.state = {      data1: [],      column1: [],      data2: [],      column2: [],      data3: [],      column3: []    };  }  componentDidMount() {    setTimeout(() => {      this.setState({        data1: d1,        column1: c1      });    }, 2000);    setTimeout(() => {      this.setState({        data2: d2,        column2: c2      });    }, 2500);    this.setState({      data3: d3,      column3: c3    });  }  render() {    return (      <>        <DataGrid data={this.state.data1} columns={this.state.column1} />        <DataGrid data={this.state.data2} columns={this.state.column2} />        <DataGrid data={this.state.data3} columns={this.state.column3} />      </>    );  }}孩子import * as React from "react";import ReactTable from "react-table";import "react-table/react-table.css";export default class DataGrid extends React.Component {  constructor(props) {    super(props);    this.state = {      showMore: false    };  }  toggleState = () => {    this.setState(prevState => ({      showMore: !prevState.showMore    }));  };
