基础使用： Layout 组件提供了24列栅格，通过在Col上添加span属性设置列所占的宽度百分比。此外，添加offset属性可以设置列的偏移宽度，计算方式与 span 相同。
<van-row>
<van-col span="8">span: 8</van-col>
<van-col span="8">span: 8</van-col>
<van-col span="8">span: 8</van-col>
</van-row>
<van-row>
<van-col span="4">span: 4</van-col>
<van-col span="10" offset="4">offset: 4, span: 10</van-col>
</van-row>
<van-row>
<van-col offset="12" span="12">offset: 12, span: 12</van-col>
</van-row>
<van-row gutter="20">
<van-col span="8">span: 8</van-col>
<van-col span="8">span: 8</van-col>
<van-col span="8">span: 8</van-col>
</van-row>
一、商品详情页面的轮播图功能实现
<!--pages/goods/index.wxml-->
<swiper indicator-dots style="height:300px;">
<block wx:for="{{goodsImages}}" wx:key="*this">
<swiper-item>
<van-image lazy-load loading="loading" fit="cover" width="100%" height="300" src="{{item.content}}" />
</swiper-item>
</block>
</swiper>
<!-- 标题及价格 -->
<view style="background-color:white;padding: 10px 15px 0;font-family:'微软雅黑'">
<view style="color:#C0A769;">
<text style="font-size:11px;">￥</text>
<text style="font-size:18px;">{{goodsData.start_price}}</text>
</view>
<van-row>
<van-col span="16">
<view style="color:black;font-size:16px;">{{goodsData.goods_name}}</view>
</van-col>
<van-col span="8" style="text-align:right;">
<view class="iconfont icon-share share"> 分享</view>
</van-col>
</van-row>
<view style="color:#939697;font-size:11px;">{{goodsData.goods_desc}}</view>
</view>
<van-cell-group border="{{false}}">
<van-cell class="buydesc" title="全程护航，请放心购买" is-link />
</van-cell-group>
/* pages/goods/index.wxss *//* miniprogram/pages/goods/index.wxss */
.price .van-cell__title{

font-size: 20pt;
}

}
.van-tag{
margin-left: 10px;
}
.van-popup{
background-color: #efefef;
}
// miniprogram/pages/goods/index.js
Page({

this.setData({

})
})
// 拉取sku规格数据
let goodsSkuDataRes = await wx.wxp.request({

})

let goodsSkuData = goodsSkuDataRes.data.data
this.setData({
