本文實例為大家分享了vue+element UI實現樹形表格的具體代碼，供大家參考，具體內容如下

一、在component文件夾下新建如下treeTable文件夾，里面有2個文件：

eval.js:將數據轉換成樹形數據

/*** @Author: jianglei* @Date: 2017-10-12 12:06:49*/’use strict’import Vue from ’vue’export default function treeToArray(data, expandAll, parent = null, level = null) { let tmp = [] Array.from(data).forEach(function(record) { if (record._expanded === undefined) { Vue.set(record, ’_expanded’, expandAll) } let _level = 1 if (level !== undefined && level !== null) { _level = level + 1 } Vue.set(record, ’_level’, _level) // 如果有父元素 if (parent) { Vue.set(record, ’parent’, parent) } tmp.push(record) if (record.children && record.children.length > 0) { const children = treeToArray(record.children, expandAll, record, _level) tmp = tmp.concat(children) } }) return tmp}

index.vue:樹形表格組件

<template> <el-table :data='formatData' :row- v-bind='$attrs'> <el-table-column v-if='columns.length===0' width='150'> <template slot-scope='scope'> <span v-for='space in scope.row._level' :key='space' /> <span v-if='iconShow(0,scope.row)' @click='toggleExpanded(scope.$index)'> <i v-if='!scope.row._expanded' /> <i v-else /> </span> {{ scope.$index }} </template> </el-table-column> <el-table-column v-for='(column, index) in columns' v-else :key='column.value' :label='column.text' :width='column.width'> <template slot-scope='scope'> <!-- Todo --> <!-- eslint-disable-next-line vue/no-confusing-v-for-v-if --> <span v-for='space in scope.row._level' v-if='index === 0' :key='space' /> <span v-if='iconShow(index,scope.row)' @click='toggleExpanded(scope.$index)'> <i v-if='!scope.row._expanded' /> <i v-else /> </span> {{ scope.row[column.value] }} </template> </el-table-column> <slot/> </el-table></template> <script>/** Auth: Lei.j1ang Created: 2018/1/19-13:59*/import treeToArray from './eval';export default { name: 'TreeTable', props: { /* eslint-disable */ data: { type: [Array, Object], required: true }, columns: { type: Array, default: () => [] }, evalFunc: Function, evalArgs: Array, expandAll: { type: Boolean, default: false } }, computed: { // 格式化數據源 formatData: function() { let tmp; if (!Array.isArray(this.data)) { tmp = [this.data]; } else { tmp = this.data; } const func = this.evalFunc || treeToArray; const args = this.evalArgs ? Array.concat([tmp, this.expandAll], this.evalArgs) : [tmp, this.expandAll]; return func.apply(null, args); } }, methods: { showRow: function(row) { const show = row.row.parent ? row.row.parent._expanded && row.row.parent._show : true; row.row._show = show; return show ? 'animation:treeTableShow 1s;-webkit-animation:treeTableShow 1s;' : 'display:none;'; }, // 切換下級是否展開 toggleExpanded: function(trIndex) { const record = this.formatData[trIndex]; record._expanded = !record._expanded; }, // 圖標顯示 iconShow(index, record) { return index === 0 && record.children && record.children.length > 0; } }};</script><style rel='stylesheet/css'>@keyframes treeTableShow { from { opacity: 0; } to { opacity: 1; }}@-webkit-keyframes treeTableShow { from { opacity: 0; } to { opacity: 1; }}</style> <style scoped>.ms-tree-space { position: relative; top: 1px; display: inline-block; font-style: normal; font-weight: 400; line-height: 1; width: 18px; height: 14px;}.ms-tree-space::before { content: '';}.processContainer { width: 100%; height: 100%;}table td { line-height: 26px;}.tree-ctrl { position: relative; cursor: pointer; color: #2196f3; margin-left: -18px;}</style>

二、在需要的地方引入該組件

例如：在component文件夾下新建a.vue:

<tree-table :data='data' :columns='columns' border/>import treeTable from './TreeTable';components: { treeTable },data() { return { columns: [ { text: '事件', value: 'event', width: 200 }, { text: 'ID', value: 'id' }, { text: '時間線', value: 'timeLine' }, { text: '備注', value: 'comment' } ], data: [ { id: 0, event: '事件1', timeLine: 50, comment: '無' }, { id: 1, event: '事件1', timeLine: 100, comment: '無', children: [ { id: 2, event: '事件2', timeLine: 10, comment: '無' }, { id: 3, event: '事件3', timeLine: 90, comment: '無', children: [{ id: 4, event: '事件4', timeLine: 5, comment: '無'},{ id: 5, event: '事件5', timeLine: 10, comment: '無'},{ id: 6, event: '事件6', timeLine: 75, comment: '無', children: [ { id: 7, event: '事件7', timeLine: 50, comment: '無', children: [ { id: 71, event: '事件71', timeLine: 25, comment: 'xx' }, { id: 72, event: '事件72', timeLine: 5, comment: 'xx' }, { id: 73, event: '事件73', timeLine: 20, comment: 'xx' } ] }, { id: 8, event: '事件8', timeLine: 25, comment: '無' } ]} ] } ] } ] }; },
