这会儿开发者工具抽风，没法发出来了。。直接贴代码吧

js:
const app = getApp()

Page({
  data: {
    test: [1, 2, 3],
    start: 6,
    end: 24,
    list: [
      {
        label: "今天",
        values: [7, 8, 9, 20, 21]
      },
      {
        label: "昨天",
        values: [10, 11, 12, 13, 14]
      },
    ]
  },
})

wxml:
<wxs module="util">
  function hasValue(values, value) {
    return values.indexOf(value) != -1
  }
  module.exports.hasValue = hasValue
</wxs>
<view class="title-column">
  <view class="title">时段</view>
  <view class="mark" wx:for="{{end-start+1}}" wx:key="$this">
    <view class="mark-start">
      <view class="mark-label">{{item+start}}</view>
      <view class="mark-line"></view>
    </view>
  </view>
</view>
<view class="value-column" wx:for="{{list}}" wx:key="label">
  <view class="title">{{item.label}}</view>
  <view class="value {{util.hasValue(item.values, hour+start)?'has-value':'not-has-value'}}" wx:for="{{end-start+1}}" wx:for-item="hour" wx:key="$this">
  </view>
</view>
