antd vue table ellipsis属性不生效

//ellipsis: true不生效代码
  <a-tooltip
        slot="status"
        slot-scope="text"
        placement="top"
        :title="text"
        :arrow-point-at-center="true"
      >
        <div>{
    
    {
    
     text }}</div>
      </a-tooltip>

//将div改为span ellipsis: true生效
  <a-tooltip
        slot="status"
        slot-scope="text"
        placement="top"
        :title="text"
        :arrow-point-at-center="true"
      >
        <span>{
    
    {
    
     text }}</span>
      </a-tooltip>

造成原因不明，有大佬了解吗？欢迎评论
