微信小程序表格实现隔行换色

微信小程序的表格样式实现隔行换色:
用三元表达式改变标签class名，
在wxss分别写不同的类名：
flex-view-itemodd
flex-view-itemeven

<view class='tablebody' wx:for="{{x'x'x}}" wx:for-item="asset">
              <view class="flex-view-item{{index%2==0? 'odd':'even'}}"> {{x'x'x}}</view>
              <view class="flex-view-item{{index%2==0? 'odd':'even'}}">{{xxx} </view>
              <view class="flex-view-item{{index%2==0? 'odd':'even'}}"> {{xxx}} </view>
              <view class="flex-view-item{{index%2==0? 'odd':'even'}}">{{xxx}}</view>
        </view>
