#### 固定表头
方便一页内展示大量数据。
需要指定 column 的 `width` 属性，否则列头和内容可能不对齐。
</cn>

<us>
#### Fixed Header
Display large amounts of data in scrollable view.
> Specify the width of each column if header and cell do not align properly.

```html
<template>
  <a-table :columns="columns" :dataSource="data" :pagination="{ pageSize: 50 }" :scroll="{ y: 240 }" />
</template>
<script>
const columns = [{
  title: 'Name',
  dataIndex: 'name',
  width: 150,
}, {
  title: 'Age',
  dataIndex: 'age',
  width: 150,
}, {
  title: 'Address',
  dataIndex: 'address',
}];

const data = [];
for (let i = 0; i < 100; i++) {
  data.push({
    key: i,
    name: `Edward King ${i}`,
    age: 32,
    address: `London, Park Lane no. ${i}`,
  });
}

export default {
  data() {
    return {
      data,
      columns,
    }
  }
