目前在鸿蒙Next系统上无法使用grid-builder，请问具体要如何替代。

<swiper class="month-view" style="height: 310px;" scroll-with-animation="{{ scrollWithAnimation }}" bindchange="onChangecurrent" current="{{current}}" indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
  <block wx:for="{{monthList}}" wx:for-index="idx" wx:for-item="monthItem" wx:key="key">
    <swiper-item class="month-item-view" style="background-color: {{item.bgColor}};">
      <scroll-view type="custom" scroll-y style="height: 100%; width: 100%;">
        <grid-builder list="{{monthItem._days}}" child-count="{{monthItem._days.length}}" cross-axis-count="7" cross-axis-gap="2" main-axis-gap="2" bind:itembuild="onItemBuild" bind:itemdispose="onItemDispose">
          <view slot:item="dayItem" slot:index style="height: 50px;">
            <m-day viewStyle="0" dataItem="{{dayItem}}" data-item="{{dayItem}}" data-index="{{index}}" bind:tap="onSelectDay"></m-day>
          </view>
        </grid-builder>
      </scroll-view>
    </swiper-item>
  </block>
</swiper>
