.waterfall{
        padding: .2rem .28rem;
        column-count: 2;   //显示两列
        column-gap: normal;  //列间距
    }
    .waterfall .item{
        width: 3.2rem;
        overflow:hidden;

        border-radius:.08rem;
        box-shadow:0px .04rem .16rem 0 rgba(0, 0, 0, 0.04);
    }
    .waterfall .item-pic{

<div class="waterfall">

            <div class="item-content">
                <div class="item-pic">
                    <img v-if="item.imageUrl1" :src="imgSrc+item.imageUrl1">
                    <img v-else src="../../image/error_img.png">
                </div>
                <div class="item-padded">
                    <div class="item-title">{
       {item.topicTitle}}</div>
                    <div class="item-desc">{
       {item.topicContent}}</div>
                    <div class="item-small tf-flex tf-flex-between tf-margin-t-10">
                        <span>{
       {item.commentCount}}评论  {
       {item.likeCount}}赞</span>
                        <span>{
       {func.time2desc(item.addTime)}}</span>
                    </div>
                </div>
            </div>
        </div>
    </div>

找了半天，发现是 item 的 margin-bottom 导致的：第一列的最后一个item的margin-bottom跑到第二列第一个item上面了，改成padding-bottom即可，因为padding属于内容，只要不折断，就不会跑到另一列
