带层级序号

在这里插入图片描述

<template><div><vxe-grid v-bind="gridOptions"></vxe-grid></div>
</template><script setup>
import { reactive } from 'vue'const gridOptions = reactive({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' }]
})
</script>

通过 tree-config.seqMode=‘increasing’ 设置为自增序号

自增序号

在这里插入图片描述

<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',seqMode: 'increasing'},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}}
