【卡顿现象】ListTable在列数较多的情况下，竖向滚动条拖动卡顿

[mzhang-eric]

ListTable 当列数较多的情况下，竖向滚动条拖动滑块会出现卡顿现象（鼠标滚轮滚动表现流畅，但拖动滑块卡顿），如下面提供的 option 设置为1W*100列可以发现拖动卡顿，实际测试发现列数超过50列也能感觉到有卡顿现象。

使用 option 如下：

 function generateRandomString(length) {
    let result = '';
    const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';
    for (let i = 0; i < length; i++) {
      result += characters.charAt(Math.floor(Math.random() * characters.length));
    }
    return result;
  }

  const generateRecords = (count) => Array.from(new Array(count)).map((_, i) => {
    const first = generateRandomString(10);
    const last = generateRandomString(4);
    return {
      id: i + 1,
      email: `${first}_${last}@xxx.com`,
      name: first,
      lastName: last,
      fullName: `${first}${last}`,
      hobbies: generateRandomString(10),
      birthday: generateRandomString(10),
      tel: generateRandomString(10),
      sex: i % 2 === 0 ? 'boy' : 'girl',
      work: i % 2 === 0 ? 'back-end engineer' : 'front-end engineer',
      city: 'beijing',
      position: 'employee',
    };
  });

  const records = generateRecords(10000);

  // 基础配置有10列
  const baseColumns = [
    {
      field: 'id',
      title: 'ID',
      width: 80,
      sort: true,
    },
    {
      field: 'email',
      title: 'email',
      width: 240,
      sort: false,
    },
    {
      field: 'fullName',
      title: 'Full name',
      width: 240,
      sort: false,
    },
    {
      field: 'hobbies',
      title: 'hobbies',
      width: 200,
    },
    {
      field: 'birthday',
      title: 'birthday',
      width: 120,
    },
    {
      field: 'sex',
      title: 'sex',
      width: 100,
    },
    {
      field: 'tel',
      title: 'telephone',
      width: 150,
    },
    {
      field: 'work',
      title: 'job',
      width: 200,
    },
    {
      field: 'city',
      title: 'city',
      width: 150,
    },
    {
      field: 'position',
      title: 'position',
      width: 150,
    },
  ];

  // 100列
  let columns = [];
  for (let i = 0; i < 10; i++) {
    columns = columns.concat(baseColumns);
  }

  const option = {
    records,
    columns,
  };
