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: [

              size: 1024,
