展示一下效果图
在components组件文件夹下新建calendarMonth文件夹
直接上代码吧：
index.wxml
{{date}} {{item}} {{x.date === today?'今天':x.day}} 记 +{{item.actualDayWage}} {{x.date === today?'今天':x.day}} 记 +{{item.actualDayWage}} {{x.date === today?'今天':x.day}} 记 +{{item.actualDayWage}} {{x.date === today?'今天':x.day}} 记 +{{item.actualDayWage}}
