waterfall怎么渲染深层数据

waterfall无法渲染深层数据造成白屏，，，，
渲染products.inputBody则渲染为[object,object]，，，，，
products.inputBody.tag则白屏，，，，

<waterfall left-gap="10" right-gap="10" column-count="2" column-gap="5" @loadmore="loadmorefun">  
    <cell v-for="(products,index) in flowList" :key="'list_'+index">  
        <view>{{products.inputBody.tag}}</view>  
    </cell>               
</waterfall>
