带有父子结构的平级数据

只需要带有父子结构的平级数据，例如：id 和 parentId，字段名可以任意设置。对于保存到数据库的平级数据非常方便，无需转换就能渲染。

<template>   <div>     <vxe-grid v-bind="gridOptions"></vxe-grid>   </div> </template>  <script> export default {   data () {     const gridOptions = {       border: true,       treeConfig: {         transform: true,         rowField: 'id',         parentField: 'parentId'       },       columns: [         { type: 'seq', width: 70 },         { field: 'name', title: 'Name', minWidth: 300, treeNode: true },         { field: 'size', title: 'Size' },         { field: 'type', title: 'Type' },         { field: 'date', title: 'Date' }       ],       data: [         { id: 10000, parentId: null, name: 'Test1', type: 'mp3', size: 1024, date: '2020-08-01' },         { id: 10050, parentId: null, name: 'Test2', type: 'mp4', size: 0, date: '2021-04-01' },         { id: 24300, parentId: 10050, name: 'Test3', type: 'avi', size: 1024, date: '2020-03-01' },         { id: 20045, parentId: 24300, name: 'Test4', type: 'html', size: 600, date: '2021-04-01' },         { id: 10053, parentId: 24300, name: 'Test5', type: 'avi', size: 0, date: '2021-04-01' },         { id: 24330, parentId: 10053, name: 'Test6', type: 'txt', size: 25, date: '2021-10-01' },         { id: 21011, parentId: 10053, name: 'Test7', type: 'pdf', size: 512, date: '2020-01-01' },         { id: 22200, parentId: 10053, name: 'Test8', type: 'js', size: 1024, date: '2021-06-01' },         { id: 23666, parentId: null, name: 'Test9', type: 'xlsx', size: 2048, date: '2020-11-01' },         { id: 23677, parentId: 23666, name: 'Test10', type: 'js', size: 1024, date: '2021-06-01' },         { id: 23671, parentId: 23677, name: 'Test11', type: 'js', size: 1024, date: '2021-06-01' },         { id: 23672, parentId: 23677, name: 'Test12', type: 'js', size: 1024, date: '2021-06-01' },         { id: 23688, parentId: 23666, name: 'Test13', type: 'js', size: 1024, date: '2021-06-01' },         { id: 23681, parentId: 23688, name: 'Test14', type: 'js', size: 1024, date: '2021-06-01' },         { id: 23682, parentId: 23688, name: 'Test15', type: 'js', size: 1024, date: '2021-06-01' },         { id: 24555, parentId: null, name: 'Test16', type: 'avi', size: 224, date: '2020-10-01' },         { id: 24566, parentId: 24555, name: 'Test17', type: 'js', size: 1024, date: '2021-06-01' },         { id: 24577, parentId: 24555, name: 'Test18', type: 'js', size: 1024, date: '2021-06-01' }       ]     }      return {       gridOptions     }   } } </script> 

带有层级结构的嵌套数据

渲染带有层级结构的数据，例如 children 存放子节点

<template>   <div>     <vxe-grid v-bind="gridOptions"></vxe-grid>   </div> </template>  <script> export default {   data () {     const gridOptions = {       border: true,       treeConfig: {         rowField: 'id',         childrenField: 'children'       },       columns: [         { type: 'seq', width: 70 },         { field: 'name', title: 'Name', minWidth: 300, treeNode: true },         { field: 'size', title: 'Size' },         { field: 'type', title: 'Type' },         { field: 'date', title: 'Date' }       ],       data: [         { id: 10000, name: 'Test1', type: 'mp3', size: 1024, date: '2020-08-01' },         {           id: 10050,           name: 'Test2',           type: 'mp4',           size: 0,           date: '2021-04-01',           children: [             {               id: 24300,               name: 'Test3',               type: 'avi',               size: 1024,               date: '2020-03-01',               children: [                 { id: 20045, name: 'Test4', type: 'html', size: 600, date: '2021-04-01' },                 {                   id: 10053,                   name: 'Test5',                   type: 'avi',                   size: 0,                   date: '2021-04-01',                   children: [                     { id: 24330, name: 'Test6', type: 'txt', size: 25, date: '2021-10-01' },                     { id: 21011, name: 'Test7', type: 'pdf', size: 512, date: '2020-01-01' },                     { id: 22200, name: 'Test8', type: 'js', size: 1024, date: '2021-06-01' }                   ]                 }               ]             }           ]         },         {           id: 23666,           name: 'Test9',           type: 'xlsx',           size: 2048,           date: '2020-11-01',           children: [             {               id: 23677,               name: 'Test10',               type: 'js',               size: 1024,               date: '2021-06-01',               children: [                 { id: 23671, name: 'Test11', type: 'js', size: 1024, date: '2021-06-01' },                 { id: 23672, name: 'Test12', type: 'js', size: 1024, date: '2021-06-01' }               ]             },             {               id: 23688,               name: 'Test13',               type: 'js',               size: 1024,               date: '2021-06-01',               children: [                 { id: 23681, name: 'Test14', type: 'js', size: 1024, date: '2021-06-01' },                 { id: 23682, name: 'Test15', type: 'js', size: 1024, date: '2021-06-01' }               ]             }           ]         },         {           id: 24555,           name: 'Test16',           type: 'avi',           size: 224,           date: '2020-10-01',           children: [             { id: 24566, name: 'Test17', type: 'js', size: 1024, date: '2021-06-01' },             { id: 24577, name: 'Test18', type: 'js', size: 1024, date: '2021-06-01' }           ]         }       ]     }     return {       gridOptions     }   } } </script>
