表格内span 垂直居中问题，应该给span也加vertical-align: middle;

.table-1 td {
    height: 1.1467rem;
    line-height: 1.1467rem;
    text-align: center;
    vertical-align: middle;
    color: #666;
    width: 50%;
}
.sure-img{
    width: 0.3467rem;
    height: 0.48rem;
    background:url(‘../../images/biddetail/icon-sure.png‘) no-repeat center;
    background-size:contain;
    display: inline-block;
    vertical-align: middle;
   
}
