vue3+ts+elementui-plus二次封装树形表格
复制粘贴即可：
一、定义table组件
<template><div class='main'><div><el-table ref="multipleTableRef" :height="height" :default-expand-all="isExpend" :data="treeTableData"style="width: 100%; margin-bottom: 20px" row-key="id" border><el-table-column :width="item.width" :fixed="item.fixed" show-overflow-tooltip align="center"v-for="(item, i) in treeTableProps" :key="i" :label="item.label"><template #default="scope"><!-- 自定义插槽展示 --><slot v-if="item.slot" :name="item.prop" :scope="scope"></slot><!-- 非自定义处理(判空) --><span v-else-if="scope.row[item.prop] === '' || scope.row[item.prop] === null">--</span><!-- 非自定义处理(正常展示) --><span v-else>{{ scope.row[item.prop] }}</span></template></el-table-column></el-table></div></div>
</template><script lang="ts" setup>
import { ref, reactive, getCurrentInstance, onMounted } from 'vue'
interface Props {// 属性名prop: string,// 属性标签label: string,// 是否固定(非必填)fixed?: boolean,// 行宽(非必填)width?: number,// 是否显示插槽(非必填)slot?: boolean,
}
const props = defineProps({/** 表格数据 */treeTableData: {type: Array,default: null,required: true},/** 表格属性 */treeTableProps: {type: Array<Props>,default: null,required: true},/** 是否默认全部展开 */isExpend: {type: Boolean,default: false,required: false},/** 表格高度 */height: {type: String,default: '60vh',required: false}
})onMounted(() => {
})</script>
<style scoped lang='less'>
//添加你想设置的样式
</style>二、在父组件中使用
<template><div class='main'><TableTree :treeTableData="tableData" :treeTableProps="treeTableProps"><!-- 插槽展示 --><template #address><el-input size="small" placeholder="Type to input" /></template></TableTree></div>
</template><script lang='ts' setup>
import TableTree from '@/components/BaseTableTree/index.vue'
import { ref, reactive, getCurrentInstance, onMounted } from 'vue'
// 定义表格数据接口
interface User {id: numberdate: stringname: stringaddress: stringhasChildren?: booleanchildren?: User[]
}
// 定义表格头部属性名
const treeTableProps = [{ prop: 'date', label: '日期', width: 300, fixed: true, },{ prop: 'name', label: '名称', },{ prop: 'address', label: '地址', slot: true, },
]
// 定义表格假数据
const tableData: User[] = [{id: 1,date: '2016-05-04',name: '',address: 'No. 189, Grove St, Los Angeles',},{id: 2,date: '2016-05-04',name: '小明',address: 'No. 189, Grove St, Los Angeles',},{id: 3,date: '2016-05-01',name: '小明',address: 'No. 189, Grove St, Los Angeles',children: [{id: 31,date: '2016-05-01',name: '小明',address: 'No. 189, Grove St, Los Angeles',children: [{id: 311,date: '2016-05-01',name: '小明',address: 'No. 189, Grove St, Los Angeles',},{id: 312,date: '2016-05-01',name: '小明',address: 'No. 189, Grove St, Los Angeles',}]},{id: 32,date: '2016-05-01',name: '小明',address: 'No. 189, Grove St, Los Angeles',},],},{id: 4,date: '2016-05-03',name: '小明',address: 'No. 189, Grove St, Los Angeles',},
]
onMounted(() => {
})</script>
