利用wx:if 及 wx:for 数据绑定来实现输出乘法口诀表的编译：
<!--index.wxml-->
<view class='con'>
<view wx:for="{{[1,2,3,4,5,6,7,8,9]}}" wx:for-item="i">
<view class='inline' wx:for="{{[1,2,3,4,5,6,7,8,9]}}" wx:for-item="j">
<view wx:if="{{j<=i}}">
{{i}}×{{j}}={{i*j}}
</view>
</view>
</view>
</view>/** index.wxss **/
.con {
font-size: 14px;
margin: 10px;
}
.inline {
display: inline-block;
width: 65px;
