vue2 el-table 封装

1. 在 custom 文件夹下面创建 tableList.vue
2. 直接上代码（代码比较多，复制可直接用）

3. 组件简单使用 （基本常用的属性方法都已封装进去 ， 可自行查看 tableList.vue ）
   （如果缺少需要的功能，可自行补充，或者留言）

/**:selecShow="true"    // 开启复选框:tableData="dataTableListInfo"   // 表格数据:theadData="option.column"  // 表格头部:fullLoading="loading"  // 表格loading@queryRow="selectDataTable"  // 表格多选事件@handleClickRow="getHandleClickRow"  // 行点击事件*/
<template><div><table-operationclass="mp-custom-table":selecShow="true":tableData="dataTableListInfo":theadData="option.column":fullLoading="loading"@queryRow="selectDataTable"@handleClickRow="getHandleClickRow"ref="tableRef">// 该字段使用了插槽  对数据做了处理<template slot="keyNode" slot-scope="{ row }"><span>{{ row['keyNode'] == 1 ? '否' : '是' }}</span></template>// 表格按钮组<el-table-column slot="operbtn" label="操作" width="160" fixed="right"><template slot-scope="{ row }"><mp-button type="text" class="mp-button_edit-custom mp-button_table-typeA-custom" @click="editFormTable(row)">编辑</mp-button><mp-button type="text" class="mp-button_edit-custom mp-button_table-typeA-custom" @click="deleteFormTable(row)">删除</mp-button></template></el-table-column></table-operation>// 分页组件<mp-pagination :pageIndex="pageIndex" :pageSize="pageSize" :total="total" @page-change="pageChange" @page-size-change="pageSizeChange"></mp-pagination></div>
</template>
<script>
import TableOperation from '@/custom/tableList' // 引入上面的表格组件
export default {components: {TableOperation,},data() {return {dataTableList: [],loading: false,pageIndex: 1, //页码pageSize: 10, //分页条目数total: 0, // 总条数option: {column: [{field: 'indexName',highlight: true,  // 鼠标移入表格行后，指标名称字段高亮   点击指标名称 跳转title: '指标名称', //  给列表的th添加提示icon，鼠标进过后显示tooltip，配置theadData时，配置headerTip内容，则展示到此，未配置不展示iconheaderTip: '检测内容定义的名称',},{field: 'indexCode',title: '唯一标识',headerTip: 'cmdb 中字段唯一标识',},{field: 'keyNode',title: '是否关键指标',headerTip: '标记',// 该字段是否使用插槽isSlot: true, //插槽}],}, // 表头}},methods:{// 编辑editFormTable(row){},deleteFormTable(row) {// 这里是表格行删除事件},// 多选selectDataTable(row, data) {},// 每一行的指标名称点击事件getHandleClickRow(row) {},// 分页pageChange(pageIndex) {this.pageIndex = pageIndex},// 分页每页条数pageSizeChange(pageSize) {this.pageIndex = 1this.pageSize = pageSize},}
}
</script>

4. 效果
   

5. 扩展（分页组件）

   1. 在 custom 文件夹下 新建 mpPagination.vue
   2. 上代码

// mpPagination.vue<template><!-- 分页 --><div class="avue-crud__pagination"><el-pagination@size-change="handleSizeChange"@current-change="handleCurrentChange":current-page="pageIndex":page-sizes="pageSizeOption":page-size="pageSize":pager-count="showPagingCount":layout="layout":total="total":key="keyIndex"></el-pagination></div>
</template><script>
export default {name: 'MpPagination',props: {index:{type:Number,default:0},//总条数total: {type: Number,default: 0,},//当前页pageIndex: {type: Number,default: 1,},//页码按钮的数量，当总页数超过该值时会折叠showPagingCount: {type: Number,default: 7,},//每页条目数pageSize: {type: Number,default: 10,},//配置功能布局layout: {type: String,default: 'total, sizes, prev, pager, next, jumper',},//选择每页条目数pageSizeOption: {type: Array,default() {return [10, 20, 50]},},},data() {return {keyIndex:0}},methods: {//每页条目数改变handleSizeChange(val) {this.$emit('page-size-change', val,this.index)},//当前页改变handleCurrentChange(val) {this.$emit('page-change', val,this.index)},},
}
</script>

6. 以上为全部代码！
