1.element-ui中使用el-tree不显示水平滚动条

            


::v-deep .el-tree-node :nth-child(2) {
    padding: 1px;
    overflow: visible;
  }

2.给树el-tree在名称后添加注释

 setUserstreeData: {
          id: "10363048910990",
          name: "dcsfzfvsdzf有限公司",
          progress: "1",
          child: [

              child: null,
              progress: "0",
            },
            {

              name: "dsavfgdsfdzsz术研究院",
              progress: "0",
              child: [

                  child: null,
                  progress: null,
                },
              ],

              ],
            },
          ],
        },

this.getTreeName(this.setUserstreeData);

 // 查找选定的项目单位id对应的二次单元

      let _this = this;
      list.forEach((item, index) => {
        let a = item;
        if (index < list.length) {
