该组件基于技术栈,主要涉及vue-cli生成的webpack项目脚手架,在此脚手架项目基础上完成的,整合了element-ui开源vue的UI项目

1.vue-cli的安装使用


npm install -g vue-cli

全局安装vue-cli之后,使用该脚手架的相关命令,可快速生成一个比较规范的vue项目结构


vue init <template-name> <project-name>

例子


vue init webpack treeTable

这样一个快速的项目结构生成,如下所示,中间一路回车就可以了,主要是设置了是否支持eslint等等

2.整合element-ui


cd treeTable

进入刚刚生成的项目目录中,安装element-ui


npm i element-ui -S

在main.js中,


import ElementUI from 'element-ui'
import 'element-ui/lib/theme-default/index.css'

Vue.use(ElementUI)

整合就可以了,具体element-ui更多的使用和操作,可以去官网查看 http://element.eleme.io/#/zh-CN/component/quickstart 我这里主要是利用他的table组件来制作一个树形结构的table。

3.树形table组件制作

在src目录的components目录中,

其中utils下面提供一些需要用的工具类

vue目录下面是组件的源码

index.js是外包入口

相关代码

dataTranslate.js主要是提供了把数组数据转换成树形结构的数据,并且进行相关属性的添加
