const data = [
  {
    key: '1',
    name: 'John Brown',

        .toString()
        .toLowerCase()
        .includes(value.toLowerCase()),
    onFilterDropdownVisibleChange: visible => {

    render: text => (
      <Highlighter
        highlightStyle={{ backgroundColor: '#ffc069', padding: 0 }}
        searchWords={[this.state.searchText]}
        autoEscape
        textToHighlight={text.toString()}
      />

  });

  handleSearch = (selectedKeys, confirm) => {
    confirm();
    this.setState({ searchText: selectedKeys[0] });

  handleReset = clearFilters => {
    clearFilters();
    this.setState({ searchText: '' });
  };

  render() {
    const columns = [
      {
        title: 'Name',
        dataIndex: 'name',
        key: 'name',
        width: '30%',
        ...this.getColumnSearchProps('name'),
      },
      {
        title: 'Age',
        dataIndex: 'age',
        key: 'age',
        width: '20%',

      {
        title: 'Address',
        dataIndex: 'address',
        key: 'address',
        ...this.getColumnSearchProps('address'),
      },
    ];
    return <Table columns={columns} dataSource={data} />;
  }
}

ReactDOM.render(<App />, document.getElementById('container'));
          

如何在handleSearch 方法里获取到dataIndex的值?
