reactjs - react-virtualized ，在哪里调用 forceUpdateGrid 来更新表格数据？

Question

在排序表数据时，我似乎无法调用原始文档forceUpdateGrid中提到的更新表数据

我收到此错误

'forceUpdateGrid' 未定义

当用户单击表头时我需要更新表数据，目前它在页面滚动后更新。我在表中有 3 列，我需要按每个列标题对表进行排序和更新

import React from 'react';
import { Column, Table, SortDirection, SortIndicator } from 'react-virtualized';
import AutoSizer from 'react-virtualized/dist/commonjs/AutoSizer';
import _ from 'underscore';
import 'react-virtualized/styles.css';

import { fakeJson } from './Data/fakeJson';

const datalist  = fakeJson;
const list = datalist; 
class TableComponent2 extends React.Component {

  constructor(){
    super();
     this.state = {
       sortBy: 'username',
       sortDirection: SortDirection.DESC,
       sortedList: list
     }
   }

   sort({ sortBy, sortDirection }) {
     console.log(list)
    const tempList = _.sortBy(list, item => item[sortBy]);
    console.log(tempList);
    const sortedList = tempList.update(
        list =>
          sortDirection === SortDirection.DESC ? list.reverse() : list
      );

    this.setState({ sortBy, sortDirection, sortedList });
    this.forceUpdateGrid;
  }

    render() {
      return (
        <AutoSizer disableHeight>
          {({ width }) => (
            <Table
              headerHeight={20}
              height={740}
              rowCount={datalist.length}

forceUpdateGrid是一个由 Table 组件公开的公共方法，您可以使用我在Tablelike上定义一个 refthis.tableRef.forceUpdateGrid

import React from 'react';
import { Column, Table, SortDirection, SortIndicator } from 'react-virtualized';
import AutoSizer from 'react-virtualized/dist/commonjs/AutoSizer';
import _ from 'underscore';
import 'react-virtualized/styles.css';

import { fakeJson } from './Data/fakeJson';

const datalist  = fakeJson;
const list = datalist; 
class TableComponent2 extends React.Component {

  constructor(){
    super();
     this.state = {
       sortBy: 'username',
       sortDirection: SortDirection.DESC,
       sortedList: list
     }
   }

   sort({ sortBy, sortDirection }) {
     console.log(list)
    const tempList = _.sortBy(list, item => item[sortBy]);
    console.log(tempList);
    const sortedList = tempList.update(
        list =>
          sortDirection === SortDirection.DESC ? list.reverse() : list
      );

    this.setState({ sortBy, sortDirection, sortedList });
    this.tableRef.forceUpdateGrid();
  }

    render() {
      return (
        <AutoSizer disableHeight>
          {({ width }) => (
            <Table
              ref={(ref) => this.tableRef = ref}
              headerHeight={20}
              height={740}
              rowCount={datalist.length}
              rowGetter={({ index }) => this.state.sortedList[index]}
              rowHeight={60}
              width={width}
              sort={this.sort}
              sortBy={this.state.sortBy}
              sortDirection={this.state.sortDirection}
            >
              <Column
                dataKey='id'
                width={200}
                flexGrow={1}
                label='ID'
              />
              <Column
                dataKey='name'
                width={200}
                flexGrow={1}
                label='NAME'
              />
              <Column
                dataKey='username'
                width={200}
                flexGrow={1}
                label='USERNAME'
              />
            </Table>
          )}
        </AutoSizer>
      );
    }
  }

  export default TableComponent2;
