大家在做后盾管理系统的时候，写的最多的可能就是表格页面了，个别分三局部：搜寻功能区、表格内容区和分页器区。个别这些性能都是应用第三方组件库实现，比如说element-ui，或者vuetify。这两个组件库都各有各的长处，但就table组件来说，我还是比拟喜爱vuetify的实现，不必手写一个个column，只有传入headers的配置数组就行，甚至分页器都内置在了table组件里，用起来非常不便。有趣味能够看看：vuetify data table。
下面是一个经典的用element-ui开发的table页面，而且理论工作中如果每个table页面都写一遍，反复代码太多了，所以无妨写一个table模板组件，缩小反复代码。我的思路是这样的：
搜寻功能区：
提供
searchBar插槽，能够自定义搜寻输入框，搜寻、重置按钮必有，新增按钮通过props管制显隐。这里对应的代码如下：genSearchBar() { if (this.noSearchBar || !this.$scopedSlots.searchBar) return ''; return ( <el-form class="seatch-form" inline={true} label-width="100"> {this.$scopedSlots.searchBar()} <el-button class="filter-item" icon="el-icon-search" type="primary" onClick={this.handleSearchBtnClick} > 查问 </el-button> <el-button class="filter-item" icon="el-icon-refresh" onClick={this.handleResetBtnClick} > 重置 </el-button> <el-button class="filter-item" icon="el-icon-plus" type="primary" v-show={this.showAddBtn} onClick={this.handleAddBtnClick} > 新增 </el-button> </el-form> );}表格内容区：
通过传入
headers主动生成columns，参数如下：{ label: '性别', prop: 'sex', width: '180', filter: 'sexFilter'}可对应如下代码：
<el-table-column prop="sex" label="性别" width="180"> <template slot-scope="scope">{{scope.row.sex | sexFilter}}</template></el-table-column>留神，只反对全局
filter。如果你想自定义
column，也提供tableColumn插槽，反对自定义column，能够如下配置：{ prop: 'action'}<el-table-column prop="action" label="操作" width="180"> <template slot-scope="scope"> <el-button>编辑</el-button> <el-button>删除</el-button> </template></el-table-column>这样，就会按传入的
prop匹配对应的column，非常不便。实现代码如下：
genTableSlot(h) { let customeColumns = this.$scopedSlots.tableColumn ? this.$scopedSlots.tableColumn() : []; return this.headers.map((item) => { // 依据item.prop判断是否应用传入的插槽内容 let foundItem = customeColumns.find( (ele) => ele.componentOptions && ele.componentOptions.propsData.prop === item.prop ); return foundItem ? foundItem : h('el-table-column', { props: { ...item, }, scopedSlots: { default: (props) => { // 依据传入的全局filter解决column数据 let filter = this.$options.filters[ item.filter ]; let itemValue = props.row[item.prop]; return h( 'span', filter ? filter(itemValue) : itemValue ); }, }, }); });}genTable(h) { return h( 'el-table', { ref: 'tableRef', props: { ...this.$attrs, data: this.data, }, on: { 'selection-change': (val) => { this.$emit('selection-change', val); }, }, }, [...this.genTableSlot(h)] );}分页器区：
如无非凡需要，分页器性能统一，所以间接内置。
实现代码如下：
genPagination() { return ( <div class="pagination-wrap"> <el-pagination layout="total,prev,pager,next,jumper" current-page={this.current} page-size={this.pageSize} total={this.total} {...{ on: { 'current-change': this.handleCurrentChange }, }} ></el-pagination> </div> );}最初附残缺代码和demo：
<script>export default { name: 'TableTemplate', props: { data: { type: Array, default: () => [], required: true, }, headers: { type: Array, default: () => [], required: true, }, current: { type: Number, default: 1, }, pageSize: { type: Number, default: 10, }, total: { type: Number, default: 0, }, noSearchBar: Boolean, showAddBtn: Boolean, }, mounted() { this.$nextTick(() => { this.$emit('search'); }); }, methods: { genSearchBar() { if (this.noSearchBar || !this.$scopedSlots.searchBar) return ''; return ( <el-form class="seatch-form" inline={true} label-width="100"> {this.$scopedSlots.searchBar()} <el-button class="filter-item" icon="el-icon-search" type="primary" onClick={this.handleSearchBtnClick} > 查问 </el-button> <el-button class="filter-item" icon="el-icon-refresh" onClick={this.handleResetBtnClick} > 重置 </el-button> <el-button class="filter-item" icon="el-icon-plus" type="primary" v-show={this.showAddBtn} onClick={this.handleAddBtnClick} > 新增 </el-button> </el-form> ); }, genTableSlot(h) { let customeColumns = this.$scopedSlots.tableColumn ? this.$scopedSlots.tableColumn() : []; return this.headers.map((item) => { // 依据item.prop判断是否应用传入的插槽内容 let foundItem = customeColumns.find( (ele) => ele.componentOptions && ele.componentOptions.propsData.prop === item.prop ); return foundItem ? foundItem : h('el-table-column', { props: { ...item, }, scopedSlots: { default: (props) => { let filter = this.$options.filters[ item.filter ]; let itemValue = props.row[item.prop]; return h( 'span', filter ? filter(itemValue) : itemValue ); }, }, }); }); }, genTable(h) { return h( 'el-table', { ref: 'tableRef', props: { ...this.$attrs, data: this.data, }, on: { 'selection-change': (val) => { this.$emit('selection-change', val); }, }, }, [...this.genTableSlot(h)] ); }, genPagination() { return ( <div class="pagination-wrap"> <el-pagination layout="total,prev,pager,next,jumper" current-page={this.current} page-size={this.pageSize} total={this.total} {...{ on: { 'current-change': this.handleCurrentChange }, }} ></el-pagination> </div> ); }, resetPagination() { this.$emit('update:current', 1); }, handleCurrentChange(val) { this.$emit('update:current', val); this.$emit('search'); }, handleSearchBtnClick() { this.$emit('search'); }, handleResetBtnClick() { this.resetPagination(); this.$emit('reset'); }, handleAddBtnClick() { this.$emit('add'); }, getTableRef() { return this.$refs.tableRef; }, }, render(h) { return ( <div> {this.genSearchBar()} {this.genTable(h)} {this.genPagination()} </div> ); },};</script><style scoped>.seatch-form { text-align: left;}.pagination-wrap { margin-top: 20px; text-align: right;}</style>Demo:
