vue el-table實現遞歸嵌套的示例代碼

說明: el-table有一個表格一級數據和二級數據顯示的是一樣的,像這種就可以用遞歸實現。
數據結構是這樣子的:

tableData:[{
	name: "Lucy",
	age: 18,
	mobile: "11111111111",
	type: 1,
	friends:[{
		name: "Lucy-friend1",
		age: 16,
		mobile: "11111111111"
	},{
		name: "Lucy-friend2",
		age: 16,
		mobile: "11111111111"
	}]
}]

像以上這種數據結構想要如下圖一樣顯示:

在這裡插入圖片描述

我用的是el-table組件,所以單獨建瞭一個組件用於表格遞歸顯示。regionTableTemplate裡expend中用到的遞歸顯示二級數據
代碼如下:

<template>
    <el-table :data="tableData" class="table-sub" ref="regionTable" :show-header="showHeader" :row-class-name="isShowExpend">
        <el-table-column type="expand">
            <template slot-scope="scope">
                <template v-if="scope.row.friends">
                    <regionTableTemplate class="in-table" :tableData="scope.row.friends" :showHeader="false"></regionTableTemplate>
                </template>
            </template>
        </el-table-column>
        <el-table-column prop="name" label="姓名"></el-table-column>
        <el-table-column prop="age" label="年齡"></el-table-column>
        <el-table-column prop="mobile" label="手機號"></el-table-column>
        <el-table-column label="操作" width="220">
            <template slot-scope="scope">
                <el-button type="text">詳情</el-button>
                <el-button type="text"> 創建可用區</el-button>
                <el-button :disabled="scope.row.type === 1?true:false" type="text">刪除</el-button>
            </template>
        </el-table-column>
    </el-table>
</template>

<script>
export default {
    name: "regionTableTemplate",
    props:{
        tableData: Array,
        showHeader: Boolean
    },
    methods:{
        //展開行  用於沒有friends數組即沒有子數據
        isShowExpend(row, index) {
            if (row.row.friends&&row.row.friends) {
                return ''
            } else {
                return 'hide-expand'
            }
        }
    }
}
</script>

<style>

</style>

父組件調用

<template>
    <div id="ops-region-wrapper">
        <div class="ops-list-wrapper">
            <table-vue :tableData="tableData" :showHeader="true" @showRegionFlag="showRegionFlag" @showDelDialog="showDelDialog"></table-vue>
            <Pager :pages='pages' @changeCurrent='changeCurrent'></Pager>
        </div>
    </div>
</template>

<script>
import Pager from '@/components/Pager.vue';
import tableVue from './components/table.vue';
export default {
    components:{
        Pager,
        tableVue
    },
    data() {
        return {
            tableData: [{
				name: "Lucy",
				age: 18,
				mobile: "11111111111",
				type: 1,
				friends:[{
					name: "Lucy-friend1",
					age: 16,
					mobile: "11111111111"
				},{
					name: "Lucy-friend2",
					age: 16,
					mobile: "11111111111"
				}]
			}],
            pages: {//分頁
                showItem: 15,
                total: 0,
                currentPage: 1
            },
        }
    },
    methods: {
        //分頁
        changeCurrent(val) {
            this.pages.currentPage = val;
        }
    },
    mounted() {
        this.getList();
    }
}
