实现逻辑：
var chunk = 10;
var len = res.data.content.length;
var result = [];
for (let i = 10; i < len; i += chunk) {
result.push(res.data.content.slice(i, i + chunk)) // 每10项分成一组
}
result = result.map((item, index) => { //遍历，每组加上表头和data
return {
columns: [{
title: ‘列号‘,
dataIndex: ‘index‘,
align: ‘center‘,
width: 60
},
{
title: ‘特征‘,
dataIndex: ‘field‘,
align: ‘center‘,
width: 110
},
{
title: ‘分类‘,
dataIndex: ‘type‘,
align: ‘center‘,
width: 110
}],
data: item
}
})
this.tableData = result
//表格渲染部分
<a-table
v-for="(item,index) in tableData"
:key="index"
:columns="item.columns"
:dataSource="item.data"
bordered
:rowKey="record=>record.id"
>
<template slot="title">
组{{index+1}}
</template>
</a-table>
