		.......
		</div>
		 <div class="rightBtn">
          <el-button
            icon="el-icon-plus"
          />
        </div>
<div>
</templete>

.jieduanbox {
  display: flex;
  align-items: center;
  overflow-x: auto; /* 当内容超出时显示横向滚动条 */
  overflow-y: hidden;
  }
  
  .rightBtn{
  flex-shrink: 0; /* 防止右侧内容缩小 */
  position: sticky;
  right: 0;
}
