<!-- 瀑布流大概的思路就是，直接定义两列等宽的view，然后两列都加载相同的数据
wx:if="{{index%2==1}}" 这里，用if来辨别是奇数还是偶数，两边加载相反的 -->
<view class="content">
<view class="left">
<block wx:for="{{noramalData.tuijain}}" wx:key="index" wx:for-item="tuijain">
<template is="{{msg1}}" data="{{tuijain}}" wx:if="{{index%2==0}}"></template>
</block>
</view>
<view class="right">
<block wx:for="{{noramalData.tuijain}}" wx:key="index" wx:for-item="tuijain">
<template is="{{msg1}}" data="{{tuijain}}" wx:if="{{index%2==1}}"></template>
</block>
</view>
