antd的table进行列筛选时，更新dataSource，为什么table显示暂无数据？

handleSearch=()=>{
  this.setState({dataSource:dataSourceB})
}

getColumnSearchProps = (dataIndex) => ({
    filterDropdown: ({
      setSelectedKeys, selectedKeys, confirm, clearFilters,
    }) => (
      <div>
        <Input
          value={selectedKeys[0]}
          onChange={e => setSelectedKeys(e.target.value ? [e.target.value] : [])}
          onPressEnter={() => this.handleSearch(selectedKeys, confirm)}
        />
        <Button
          onClick={() => this.handleSearch(selectedKeys, confirm)}
        >
          Search
        </Button>
      </div>
    ),
    //筛选条件，没有写代码，所以没有数据返回，所以是暂无数据
    onFilter: (value, record) =>{  },
  })

render{
  return(
    <Table
      column={ [{...this.getColumnSearchProps('name')}}
      dataSource={dataSourceA}
    >
  ) 

}

 getLocalData(state?: TableState<T> | null, filter: boolean = true): Array<T> {
    const currentState: TableState<T> = state || this.state;
    const { dataSource } = this.props;
    let data = dataSource || [];
    // 优化本地排序
   //就是这行代码，通过slice，另开内存来保存dataSource
    data = data.slice(0);
    const sorterFn = this.getSorterFn(currentState);
    if (sorterFn) {
      data = this.recursiveSort(data, sorterFn);
    }
    // 筛选
    if (filter && currentState.filters) {
      Object.keys(currentState.filters).forEach(columnKey => {
        const col = this.findColumn(columnKey) as any;
        if (!col) {
          return;
        }
        const values = currentState.filters[columnKey] || [];
        if (values.length === 0) {
          return;
        }
        const onFilter = col.onFilter;
        data = onFilter
          ? data.filter(record => {
              return values.some(v => onFilter(v, record));
            })
          : data;
      });
    }
    return data;
  }
