Steps to Reproduce

1、执行以下代码
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;
}
function generateRandomHobbies() {
const hobbies = [
'Reading books',
'Playing video games',
'Watching movies',
'Cooking',
'Hiking',
'Traveling',
'Photography',
'Playing musical instruments',
'Gardening',
'Painting',
'Writing',
'Swimming'
];

const numHobbies = Math.floor(Math.random() * 3) + 1; // 生成 1-3 之间的随机整数
const selectedHobbies = [];

for (let i = 0; i < numHobbies; i++) {
const randomIndex = Math.floor(Math.random() * hobbies.length);
const hobby = hobbies[randomIndex];
selectedHobbies.push(hobby);
hobbies.splice(randomIndex, 1); // 确保每个爱好只选一次
}

return selectedHobbies.join(', ');
}
function generateRandomBirthday() {
const start = new Date('1970-01-01');
const end = new Date('2000-12-31');
const randomDate = new Date(start.getTime() + Math.random() * (end.getTime() - start.getTime()));
const year = randomDate.getFullYear();
const month = randomDate.getMonth() + 1;
const day = randomDate.getDate();
return ${year}-${month < 10 ? '0' + month : month}-${day < 10 ? '0' + day : day};
}

function generateRandomPhoneNumber() {
const areaCode = ['130', '131', '132', '133', '134', '135', '136', '137', '138', '139', '150', '151', '152', '153', '155', '156', '157', '158', '159', '170', '176', '177', '178', '180', '181', '182', '183', '184', '185', '186', '187', '188', '189'];
const prefix = areaCode[Math.floor(Math.random() * areaCode.length)];
const suffix = String(Math.random()).substr(2, 8);
return prefix + suffix;
}

const generatePersons = (count) => {
return Array.from(new Array(count)).map((_, i) => {
const first=generateRandomString(10);
const last=generateRandomString(4);
return {
id: i+1,
email1: ${first}_${last}@xxx.com,
name: first,
lastName: last,
hobbies: generateRandomHobbies(),
birthday: generateRandomBirthday(),
tel: generateRandomPhoneNumber(),
sex: i % 2 === 0 ? 'boy' : 'girl',
work: i % 2 === 0 ? 'back-end engineer' : 'front-end engineer',
city: 'beijing',
}});
};

const records = generatePersons(10000000);
const columns = [
{
field: 'id',
title: 'ID',
width: 80,
sort: true,
},
{
field: 'email1',
title: 'email',
width: 250,
sort: false,
},
{
field: 'full name',
title: 'Full name',
columns: [
{
field: 'name',
title: 'First Name',
width: 120,
},
{
field: 'lastName',
title: 'Last Name',
width: 100,
},
],
},
{
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,
},
];
const option = {
records,
columns,
transpose: true
};
const tableInstance = new VTable.ListTable(document.getElementById(CONTAINER_ID),option);
window['tableInstance'] = tableInstance;
2、把表格滚动至底部，发现有空白
