vue3 实现关于 el-table 表格组件的封装及调用方法

一、示例图:

二、组件

type TProps = { tableData: any[] columns: any[], colorType: number, // 颜色类型 isExistSelect: boolean // 是否存在筛选项 } const props = withDefaults(defineProps(), {}) const tableRowClassName = ({ rowIndex }: { rowIndex: number }) => { if (rowIndex % 2 === 1) { return props.colorType === 1 ? 'odd-row' : 'class-odd-row' } else { return props.colorType === 1 ? 'even-row' : 'class-even-row' } } .bg-scroll { border-radius: 10px; height: 96%; overflow-y: scroll; &::-webkit-scrollbar { width: 5px; height: 0 !important; } &::-webkit-scrollbar-thumb { border-radius: 10px; background: #eeeeee; } } .sn-table { padding: 0 10px 0 20px; :deep(.el-table) { color: #ffffff !important; tr { td { border: none; padding: 16px 0; font-size: 15px; } } th.el-table__cell { background: #141414 !important; border: none; color: #00B386; font-size: 14px; font-weight: 400; } .even-row { background-color: #333 !important; } .odd-row { background-color: #141414 !important; } .class-even-row { background-color: #333 !important; } .class-odd-row { background-color: #00B386 !important; } } :deep(.el-scrollbar__wrap--hidden-default) { background: #141414 !important; } :deep(.el-table--enable-row-hover) { .el-table__body { tr:hover>td.el-table__cell { color: #8C8C8C; background: #333 !important; } } } :deep(.el-table__inner-wrapper) { &::before { background-color: transparent; } } :deep(.el-table .ascending .sort-caret.ascending){ border-bottom-color:#00B386 !important; } :deep(.el-table .descending .sort-caret.descending){ border-top-color:#00B386 !important; } .ok-text{ font-size: 35px; font-weight: 300; } .tag-list{ width: 100%; padding: 2px 0; .tag-btn{ border-radius: 5px; border: 1px solid #EF8714; color: #EF8714; padding: 1px 10px; margin-right: 15px; &:last-child{ margin-right: 0; } } } } :deep(.el-progress){ width: 185px; margin: 0 auto; } :deep(.el-progress__text){ span{ font-size: 16px; } } :deep(.el-progress-bar__outer){ background: #D9D9D9; }

三、页面调用

import { onMounted, ref } from 'vue'
import CanvasVideo from "@/components/CanvasVideo.vue"
const knowInfo = ref([])
const knowColumns = ref([])
onMounted(()=>{
    init()
})
//数据处理
const init = () => {
    const datas = ref([
        {studentName:'陈佳颖',correctRate:0,noAnswerCount:13},
        {studentName:'丁靖芸',correctRate:0,noAnswerCount:13},
        {studentName:'谷雨恒',correctRate:0,noAnswerCount:13},
        {studentName:'欧阳江源',correctRate:0,noAnswerCount:13},
        {studentName:'任行宽',correctRate:0,noAnswerCount:13},
        {studentName:'任彦宇',correctRate:0,noAnswerCount:13},
        {studentName:'王骁南',correctRate:0,noAnswerCount:13},
        {studentName:'吴骏扬',correctRate:0,noAnswerCount:13}
    ])
    if (datas && datas.length > 0) {
        datas.forEach((it: any, index:number) => {
            knowInfo.value.push({
                '行号': index+1,
                '姓名': it.studentName,
                '正确率': it.correctRate,
                '未答题数': it.noAnswerCount
            })
        })
        for (const key in knowInfo.value[0]) {
            knowColumns.value.push({
                keyName: key,
                width: key === '行号' ? 140 : null
            })
        }
    }
}

四、其他

(1)自定义标题

           姓名
        

(2)自定义下标

            {{$index+1}}
        

(3)自定义内容

{{scope.row.name}}s

(4)添加排序(升序、降序)


(5)多选与单选

1. 单选

import { ref } from "vue"
const multipleTable = ref()
const handleList = ref([])
// 设置单选||显示高亮
const rowselect = (row:any) => {
  multipleTable.value.toggleRowSelection(row)
}
// 选择多个单选框,只取最后选中的那一个
const selectGroupChange = (row:any) => {
  if (row.length > 1) {
    multipleTable.value.clearSelection()
    multipleTable.value.toggleRowSelection(row.pop())
    return
  }
  if (row.length == 1) {
    handleList.value = row
  } else {
    handleList.value = []
  }
}

// 隐藏表头选择框
:deep(.el-table__header){
  .el-checkbox{
    display: none;
  }
}

2. 多选

// 选择多个选择框
const handleSelectionChange = (selecteds: any, row: any) => {}
// 全选
const handleAllChange= (row:any) => {}

五、实例(实现树形数据与懒加载)

示例图:通过点击当前节点,调用接口展示下一节点,实现列表的增删改查

1、添加修改组件 EditForm.vue

import { getChildrens, getDictionaryInfo, EditDictionary } from '@/api/dictionary' import rules from '@/utils/rules' export default { props: { id: { type: Number, default: 0 }, title: { type: String, default: '' } }, data() { return { menuTree: [], // 字典树 rules: rules, formLabelWidth: '120px', size: 'small', loading: false, form: { id: this.id, parentId: 0, parentDictionaryName: '', dictionaryCode: '', dictionaryName: '', remark: '', deleteState: true } } }, created() { this.fetchInitData() }, methods: { handlePagedCallback() { this.$emit('handlePagedCallback') }, handleSubmitForm() { this.$refs['menuEditForm'].validate((valid) => { if (valid) { this.loading = true EditDictionary(this.form).then((res) => { this.loading = false if (res.code === 200) { if (res.data) { this.$message.success('操作成功') this.handlePagedCallback() } else { this.$message.error('操作失败') } } else { this.$message.error(res.message) } }) } }) }, handleResetForm() { if (this.$refs['menuEditForm']) { this.$refs['menuEditForm'].resetFields() } }, fetchInitData() { getChildrens().then((res) => { if (res.code === 200) { this.menuTree = JSON.parse(JSON.stringify(res.data).replace(/id/g, 'value').replace(/dictionaryName/g, 'label')) this.fetchFormData() } }) }, fetchFormData() { this.handleResetForm() if (this.id !== 0) { const id = { Id: this.id } getDictionaryInfo(id).then((res) => { if (res.code === 200) { this.form = Object.assign(this.form, res.data) } }) } } } }

2、主页面 index.vue

查询
新增修改删除
取 消确 定
import Pagination from '@/components/Pagination' import EditForm from './EditForm' import { getDictionaryNext, getDictionaryRoute, DeleteDictionaryRoute } from '@/api/dictionary' export default { components: { Pagination, EditForm }, data() { return { search: { keyword: '' }, searchId: 0, // 表格数据 table: { data: [], selectRows: [], border: false }, currChildren: [], // 分页数据 pagination: { index: 1, size: 20, total: 0 }, // 弹出层 dialog: { close: false, // 是否关闭 edit: { id: 0, title: '修改字典', // 弹出层title visible: false, // 弹出层是否显示 width: '800px' // 弹出层宽度 } }, layzNode: null, layztreeNode: null, layzresolve: null } }, created() { this.getDictionaryList() }, methods: { lazyload(tree, treeNode, resolve) { if (tree) { var data = { Id: tree.id } getDictionaryNext(data).then((res) => { if (res.code === 200) { this.layzNode = tree this.layztreeNode = treeNode this.layzresolve = resolve resolve(res.data) } }) } }, Submit() { this.$refs.Submit.handleSubmitForm() }, // 勾选 handleSelectionChange(selection) { this.table.selectRows = selection }, // 新增 AddDialog() { this.dialog.edit.id = 0 this.dialog.edit.title = '添加字典' this.dialog.edit.visible = true }, // 修改 EditDialog() { if (this.table.selectRows.length !== 1) { this.$message.warning('请选择要修改的字典') } else { this.dialog.edit.id = this.table.selectRows[0].id this.dialog.edit.title = '修改字典' this.dialog.edit.visible = true } }, // 修改成功回调 handleEditCallback() { this.dialog.edit.visible = false this.dialog.edit.id = 0 this.$nextTick(() => { this.$set(this.$refs.myTable.store.states.lazyTreeNodeMap, this.layzNode.id, []) this.lazyload(this.layzNode, this.layztreeNode, this.layzresolve) this.getDictionaryList() }) }, // 删除 handleDelete() { if (this.table.selectRows.length === 0) { this.$message.warning('未勾选记录') return } const ids = [] this.table.selectRows.forEach((it) => { ids.push(it.id) }) this.$confirm('此操作将永久删除勾选记录, 是否继续?').then(() => { DeleteDictionaryRoute(ids).then((res) => { if (res.code === 200) { if (res.data) { this.$nextTick(() => { this.getDictionaryList() this.$set(this.$refs.myTable.store.states.lazyTreeNodeMap, this.layzNode.id, []) this.lazyload(this.layzNode, this.layztreeNode, this.layzresolve) }) this.$message.success('操作成功') } else { this.$message.error('操作失败') } } else { this.$message.error(res.message) } }) }) }, // 列表接口 getDictionaryList() { var data = { searchName: this.search.keyword, searchId: this.searchId, pageIndex: this.pagination.index, pageSize: this.pagination.size } getDictionaryRoute(data).then((res) => { if (res.code === 200) { this.pagination.total = res.data.total this.table.data = res.data.data } }) }, // 重载表格 handleReloadPaged() { this.pagination.index = 1 this.getDictionaryList() }, // 分页变更 handlePaginationChange(data) { this.pagination.index = data.current this.pagination.size = data.pageSize this.getDictionaryList() } } }
