vue3 甘特图（一）

　　1.功能使用背景：

　　　　　　甘特图是一种项目管理工具，以图形直观的方式显示项目的时间轴和任务计划

　　2.vue3 初始化甘特图 gantt

　　　　2.1 下载安装 dhtmlx-gantt 依赖包

npm install dhtmlx-gantt -save

　　　　2.2 引入插件

import { gantt } from 'dhtmlx-gantt'
import 'dhtmlx-gantt/codebase/dhtmlxgantt.css'
import demoData from './ganttData.json'

　　　　2.3 初始化及其简单配置测试数据

//初始化甘特图
const initGantt = () => {
  gantt.config.grid_width = 350
  gantt.config.add_column = false //添加符号

  //时间轴图表中，如果不设置，只有行边框，区分上下的任务，设置之后带有列的边框，整个时间轴变成格子状。
  gantt.config.autofit = false
  gantt.config.row_height = 60
  gantt.config.bar_height = 34
  // gantt.config.fit_tasks = true //自动延长时间刻度，以适应所有显示的任务
  gantt.config.auto_types = true //将包含子任务的任务转换为项目，将没有子任务的项目转换回任务
  // gantt.config.xml_date = '%Y-%m-%d' //甘特图时间格式
  gantt.config.readonly = true //是否只读
  gantt.i18n.setLocale('cn') //设置语言
  gantt.init('gantt_here')
  gantt.parse(demoData)
}
