Alternatively you can implement drag sorting with handler using react-sortable-hoc.

import { Table } from 'antd';
import { SortableContainer, SortableElement, SortableHandle } from 'react-sortable-hoc';
import { MenuOutlined } from '@ant-design/icons';
import { arrayMoveImmutable } from 'array-move';

const DragHandle = SortableHandle(() => <MenuOutlined style={{ cursor: 'grab', color: '#999' }} />);

const columns = [
  {
    title: 'Sort',
    dataIndex: 'sort',
    width: 30,
    className: 'drag-visible',
    render: () => <DragHandle />,
  },
  {
    title: 'Name',
    dataIndex: 'name',
    className: 'drag-visible',
  },
  {
    title: 'Age',
    dataIndex: 'age',
  },
  {
    title: 'Address',
    dataIndex: 'address',
  },

const data = [

    key: '1',
    name: 'John Brown',
    age: 32,

      />
    );

ReactDOM.render(<SortableTable />, mountNode);

.row-dragging {

.row-dragging td {
  padding: 16px;
