在vue中element ui 结合frappe-gantt实现一个简单的甘特图功能_element ui 甘特图

1. 在vue中创建甘特图步骤请参考： https://editor.csdn.net/md/?articleId=130145782

2. 结合element ui 实现甘特图功能

实现效果：

2.1 下载element ui

因为我是在vue3中，所以下载element-plus 执行 npm i element-plus --save
main.js 里引入element ui

import { createApp } from 'vue'

import ElementPlus from 'element-plus';//1.引入组件
import 'element-plus/theme-chalk/index.css';//2.引入CSS
import locale from 'element-plus/lib/locale/lang/zh-cn';
import App from './App.vue';

createApp(App).use(ElementPlus, { locale }).mount('#app')

2.2. 创建Gantt.vue组件

<template>
  <div class="gantt-container">
    <el-row>
      <el-col :span="8">
        <el-table
          :data="tasks"
          stripe
          style="width: 100%"
          row-key="id"
          border
          lazy
          :load="load"
          :tree-props="{ children: 'children', hasChildren: 'hasChildren' }"
        >
          <el-table-column prop="name" width="160" label="任务名称" show-overflow-tooltip />
          <el-table-column prop="start" width="140" label="开始日期" show-overflow-tooltip />
