求助！！！！

求助大神帮我看看这段代码中，为什么瀑布流中没有数据显示，数据都通过接口正确查询出来了。

	<view class="waterfall">
		<!-- 搜索框 -->
		<u-search v-model="keywords" @change="searchBtn" :show-action="true" action-text="搜索"
			:animation="true"></u-search>

		<view class="tab-strickt">
			<u-tabs active-color="#00aaff" name="categoryName" count="cate_count" :list="tabList" :is-scroll="true"
				v-model="current" @change="change"></u-tabs>
		</view>
		<!-- <view class="u-waterfall"> -->
			<u-waterfall v-model="flowList" ref="uWaterfall1">
					<view class="demo-warter" v-for="(item, index) in flowList" :key="index">
						<!-- 警告：微信小程序中需要hx2.8.11版本才支持在template中结合其他组件，比如下方的lazy-load组件 -->
						<view class="demo-demandsName">
							{{item.demandsName}}
						</view>
						<view class="demo-demandsDesc">
							{{item.demandsDesc}}
						</view>
						<view class="demo-businessName">
							{{item.businessName}}
						</view>
						<view class="demo-categoryName">
							{{item.categoryName}}
						</view>
						<view class="demo-createTime">
							{{item.createTime}}
						</view>
					</view>
			</u-waterfall>
		<!-- </view> -->
		<u-loadmore bg-color="rgb(240, 240, 240)" :status="loadStatus" @loadmore="loadMore"></u-loadmore>
	</view>
</template>
