我要实现将数据存储为csv文件，现在想到的方案是将数据转成csv格式的字符串，然后创建.csv文件后写入。如果没办法实现这个功能的话有没有其他实现方法？

我要做一个及时渲染的表格，但是使用setData传入数据后发现wx:for没有渲染出表格的数据 [图片] [图片] //js onShow(){     this.setData({       content:app.globalData.content,       getweigh:app.globalData.getweigh     })     console.log(this.data.getweigh);             } //wxml  <view class="tr" wx:for="{{getweigh}}">       <view class="td_1">{{index+1}}</view>       <view class="td">{{getweigh[index].WeighNumber}}</view>       <view class="td">{{getweigh[index].CardNumber}}</view>       <view class="td">{{getweigh[index].Time1+''}}</view>       <view class="td">{{getweigh[index].CarNumber}}</view>       <view class="td">{{getweigh[index].CabientNumber}}</view>       <view class="td">{{getweigh[index].GrossWeight}}</view>       <view class="td">{{getweigh[index].Tare}}</view>       <view class="td">{{getweigh[index].NetWeight}}</view>       <view class="td">{{getweigh[index].Business}}</view>       <view class="td">{{getweigh[index].WeighMethod}}</view>       <view class="td">{{getweigh[index].GoodsName}}</view>       <view class="td">{{getweigh[index].Specifications}}</view>       <view class="td">{{getweigh[index].ForwardUnit}}</view>       <view class="td">{{getweigh[index].Consignee}}</view>       <view class="td">{{getweigh[index].TransportUnit}}</view>       <view class="td">{{getweigh[index].Note}}</view>       <view class="td">{{getweigh[index].WeighMan}}</view>     </view> 刷新一下之后才渲染出来 [图片]
