vue封装element中table组件
后台系统,table被用的次数比较多,所以决定提出来作为组件
1.新建一个Table.vue文件
<!--region 封装的分页 table--> <template> <div class="table"> <el-table id="iTable" v-loading.iTable="options.loading" :data="list" :stripe="options.stripe" ref="mutipleTable" @selection-change="handleSelectionChange"> <!--region 选择框--> <el-table-column v-if="options.mutiSelect" type="selection" style="width: 55px;"> </el-table-column> <!--endregion--> <!--region 数据列--> <template v-for="(column, index) in columns"> <el-table-column :prop="column.prop" :key='column.label' :label="column.label" :align="column.align" :width="column.width"> <template slot-scope="scope"> <template v-if="!column.render"> <template v-if="column.formatter"> <span v-html="column.formatter(scope.row, column)"></span> </template> <template v-else> <span>{{scope.row[column.prop]}}</span> </template> </template> <template v-else> <expand-dom :column="column" :row="scope.row" :render="column.render" :index="index"></expand-dom> </template> </template> </el-table-column> </template> <!--endregion--> <!--region 按钮操作组--> <el-table-column ref="fixedColumn" label="操作" align="center" :width="operates.width" :fixed="operates.fixed" v-if="operates.list.filter(_x=>_x.show === true).length > 0"> <template slot-scope="scope"> <div class="operate-group"> <template v-for="(btn, key) in operates.list"> <div class="item" v-if="btn.show" :key='btn.id'> <el-button :type="btn.type" size="mini" :icon="btn.icon" :disabled="btn.disabled" :plain="btn.plain" @click.native.prevent="btn.method(key,scope.row)">{{ btn.label }} </el-button> </div> </template> </div> </template> </el-table-column> <!--endregion--> </el-table> </div> </template> <!--endregion--> <script> export default { props: { list: { type: Array, default: [] }, // 数据列表 columns: { type: Array, default: [] }, // 需要展示的列 === prop:列数据对应的属性,label:列名,align:对齐方式,width:列宽 operates: {}, // 操作按钮组 === label: 文本,type :类型(primary / success / warning / danger / info / text),show:是否显示,icon:按钮图标,plain:是否朴素按钮,disabled:是否禁用,method:回调方法 options: { type: Object, default: { stripe: false, // 是否为斑马纹 table highlightCurrentRow: false // 是否要高亮当前行 }, } // table 表格的控制参数 }, //组件 components: { expandDom: { functional: true, props: { row: Object, render: Function, index: Number, column: { type: Object, default: null } }, render: (h, ctx) => { const params = { row: ctx.props.row, index: ctx.props.index } if (ctx.props.column) params.column = ctx.props.column return ctx.props.render(h, params) } } }, // 数据 data () { return { pageIndex: 1, multipleSelection: [] // 多行选中 } }, mounted () { }, computed: { }, methods: { // 多行选中 handleSelectionChange (val) { this.multipleSelection = val this.$emit('handleSelectionChange', val) }, // 显示 表格操作弹窗 showActionTableDialog () { console.log(4444) this.$emit('handelAction') } } } </script> <style lang="scss" > </style>
2.调用组件
<template> <div class="table-page"> <i-table :list="list" @handleSelectionChange="handleSelectionChange" :options="options" :columns="columns" :operates="operates" > </i-table> </div> </template> <script> import iTable from '../components/Table' export default { components: {iTable}, data () { return { list: [ { id: '24', title: '编号3', state:0 }, { id: '23', title: '编号3', state:1 }, { id: '23', title: '编号3', state:2 }, { id: '2', title: '编号3', state:0 }, { id: '223', title: '编号3', state:1 }, { id: '2444', title: '编号3', state:1 }, ], // table数据 options: { stripe: true, // 是否为斑马纹 table loading: false, // 是否添加表格loading加载动画 highlightCurrentRow: true, // 是否支持当前行高亮显示 mutiSelect: true, // 是否支持列表项选中功能 }, // table 的参数 columns: [ { prop: 'id', label: '编号', align: 'center', }, { prop: 'title', label: '标题', align: 'center', formatter: (row, column, cellValue) => { return `<span style="white-space: nowrap;color: dodgerblue;">${row.title}</span>` } }, { prop: 'state', label: '状态', align: 'center', render: (h, params) => { return h('el-tag', { props: {type: params.row.state === 0 ? 'success' : params.row.state === 1 ? 'info' : 'danger'} // 组件的props }, params.row.state === 0 ? '上架' : params.row.state === 1 ? '下架' : '审核中') } }, ], // 需要展示的列 operates: { width: 200, fixed: 'right', list: [ { id:'1', label: '编辑', type: 'warning', show: true, icon: 'el-icon-edit', plain: true, disabled: false, method: (index, row) => { this.handleEdit(index, row) } }, { id:'2', label: '删除', type: 'danger', icon: 'el-icon-delete', show: true, plain: false, disabled: false, method: (index, row) => { this.handleDel(index, row) } } ] } // 列操作按钮 } }, methods: { // 选中行 handleSelectionChange (val) { console.log('val:', val) }, // 编辑 handleEdit (index, row) { console.log(' index:', index) console.log(' row:', row) }, // 删除 handleDel (index, row) { console.log(' index:', index) console.log(' row:', row) } } } </script>
