Header scrollLeft set to 0 when adding a new column

code:

import React from 'react';
import Table from 'rc-table';
import '../../assets/index.less';

const columns = [
  { title: 'title1', dataIndex: 'a', key: 'a', width: 100 },
  { title: 'title2', dataIndex: 'b', key: 'b', width: 100 },
  { title: 'title3', dataIndex: 'c', key: 'c', width: 100 },
  { title: 'title4', dataIndex: 'b', key: 'd', width: 100 },
  { title: 'title5', dataIndex: 'b', key: 'e', width: 100 },

  { title: 'title9', dataIndex: 'b', key: 'i', width: 100 },
  { title: 'title10', dataIndex: 'b', key: 'j', width: 100 },
  { title: 'title11', dataIndex: 'b', key: 'k', width: 100 },
  { title: 'title12', dataIndex: 'b', key: 'l', width: 100 },
];

const data = [
  { a: '123', b: 'xxxxxxxx xxxxxxxx', d: 3, key: '1' },
  { a: 'cdd', b: 'edd12221 edd12221', d: 3, key: '2' },
  { a: '133', c: 'edd12221 edd12221', d: 2, key: '3' },

  { a: '133', c: 'edd12221 edd12221', d: 2, key: '8' },
  { a: '133', c: 'edd12221 edd12221', d: 2, key: '9' },

expect

header and body remain the same position when adding a column

Start with the provided Demo reproduction using the Table component, horizontal scrolling, and the add-column action. Trace how the header and body scroll positions are handled when the columns change, then verify that adding a column leaves both positions unchanged.
