Vant中List列表下拉加载更多

van-list上只有一层父级元素div，多了可能下拉加载出不来；或者更多

<template>
    <div class="scholl-declarepage">
	
        <van-list
            v-model="loading"
            :finished="finished"
            finished-text="没有更多了"
            @load="onLoad"
            :immediate-check="cheack"
            >
			
                <swipe-cell
                custom
                class="bootom-having-border"
                :isEdit="isEdit"
                v-for="(item,index) in listAchool" :key="index"
                @edit="detior(item)"
                @remove="delItem(item)"
                >
                    <scholl-list-com :listObj="item" @gotodetails="gotodetails(item)"></scholl-list-com>
                </swipe-cell>
            </van-list>  
    </div>
