vue-element如何使用vue-table-with-tree-grid树形表格

有时我们需要使用折叠树形表格，比如以下形式

这个功能主要用到这个插件vue-table-with-tree-grid

1、插件下载地址：https://github.com/MisterTaki/vue-table-with-tree-grid

安装：

npm方式:

npm i vue-table-with-tree-grid -S

或者yarn方式 :

yarn add vue-table-with-tree-grid

2、引入方式：

安装好之后，在main.js下引入

import TreesTable from 'vue-table-with-tree-grid'
Vue.component('tree-table', TreesTable)

3、使用方法

<!-- 卡片视图 -->
        <el-card>
          <tree-table :data="authList" :columns="columns" :selection-type="false"
           :expand-type="false" 
          :show-index="true" index-text="序号" border>
          <!-- 等级模板 -->
            <template slot="levelss" slot-scope="scope">
              <el-tag v-if="scope.row.level=='0'">一级</el-tag>
              <el-tag v-if="scope.row.level=='1'" type="success">二级</el-tag>
              <el-tag v-if="scope.row.level=='2'" type="warning">三级</el-tag>
            </template>
          </tree-table>
        </el-card>

4、接口请求，模板赋值

<script>
export default {
  data () {
    return {
      // 权限列表
      authList: [],
      columns: [
          {
            label: '权限名称',
            prop: 'name',
          },
          {
            label: '路径',
            prop: 'path',
          },
          {
            label: '权限等级',
            type: 'template',
            template: 'levelss',
          }
        ]
    }
  },
  created () {
    // 获取所有权限
    this.getAuth()
  },
  methods: {
    // 获取权限列表
    async getAuth () {
      const { data: res } = await this.$http.get('permission/auth')
      if (res.code != 0) { this.$message.error(res.msg) }
      this.authList = res.data
      console.log(res.data)
    }
  }
}
</script>

接口返回数据格式

{
    "code": 0,
    "msg": "成功",
    "data": [
        {
            "id": 2,
            "name": "系统管理",
            "path": "",

                            "pid": 6,
                            "route_name": "admin.user.userEdit",

                        },
                        {
                            "id": 14,
                            "name": "管理员状态编辑",
                            "path": null,
                            "pid": 6,
                            "route_name": "admin.user.edit",
                            "icon": "",
                            "is_menu": 1,
                            "level": 2
                        }
                    ]
                 }
            ]
