element中Table表格控件实现单选功能、多选功能、两种分页方式

1、Table表格控件实现单选功能

<template>
    <div>
        <!-- highlight-current-row  是否要高亮当前行 -->
        <!-- row-click  当某一行被点击时会触发该事件 -->
        <el-table :data="tableData" style="width: 100%" @row-click="singleElection" highlight-current-row>
            <el-table-column align="center" min-width="55" label="选择">
                <template slot-scope="scope">
                    <!-- 可以手动的修改label的值，从而控制选择哪一项 -->
                    <!-- 注意：这里写 &nbsp 的目的是为了页面不显示内容，只显示单选操作 -->
                    <el-radio class="radio" v-model="templateSelection" :label="scope.row.id">&nbsp;</el-radio>
                </template>
            </el-table-column>
            <el-table-column align="center" prop="id" label="编号" min-width="80">
            </el-table-column>
            <el-table-column align="center" prop="date" label="日期" min-width="150">
            </el-table-column>
            <el-table-column align="center" prop="name" label="姓名" min-width="80">
            </el-table-column>
            <el-table-column align="center" prop="address" label="地址" min-width="250"></el-table-column>
        </el-table>
    </div>
</template>
  
<script>
export default {
    name: "TablePage",
    data() {
        return {
            tableData: [
                {
                    id: "0001",
                    date: "2016-05-02",
                    name: "王小虎",
                    address: "上海市普陀区金沙江路 1518 弄",
                },
                {
                    id: "0002",
                    date: "2016-05-04",
                    name: "王小虎",
                    address: "上海市普陀区金沙江路 1517 弄",
                },
                {
                    id: "0003",
                    date: "2016-05-01",
                    name: "王小虎",
                    address: "上海市普陀区金沙江路 1519 弄",
                },
                {
                    id: "0004",
                    date: "2016-05-03",
                    name: "王小虎",
                    address: "上海市普陀区金沙江路 1516 弄",
                },
            ],
            //   当前选择的行的id
            templateSelection: "",
            //   当前选择的行的数据
            checkList: [],
        };
    },
    methods: {
        singleElection(row) {
            this.templateSelection = row.id;
            this.checkList = this.tableData.filter((item) => item.id === row.id);
            console.log(`该行的编号为${row.id}`);
        },
    },
};
</script>

2、Table控件和Pagination控件实现多选和两种分页方式

方法一：使用slice方法

一次调用后端接口返回所有数据list，然后使用list.slice((pageNum - 1) * pageSize, pageNum * pageSize)使得数据根据页码改变 ;

方法二：多次调用接口

每次换页都调用接口，后端每次返回该页的数据
<template>
<el-table :row-key="getRowKey" @row-click="clickRow" ref="table" @selection-change="handleSelectionChange" :data="list.slice((pageNum - 1) * pageSize, pageNum * pageSize)"> <el-table-column label="序号" type="index" align="center"> <template slot-scope="scope"> {{ (pageNum - 1) * pageSize + scope.$index + 1 }} </template> </el-table-column> <el-table-column type="selection" :reserve-selection="true" width="55"></el-table-column> <el-table-column align="center" prop="id" label="编号" min-width="80"> </el-table-column> <el-table-column align="center" prop="date" label="日期" min-width="150"> </el-table-column> <el-table-column align="center" prop="name" label="姓名" min-width="80"> </el-table-column> <el-table-column align="center" prop="address" label="地址" min-width="250"></el-table-column> </el-table>
<el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="pageNum" :page-sizes="[2, 5, 10, 15]" :page-size="pageSize" layout="total, sizes, prev, pager, next, jumper" :total="total"> </el-pagination>
```
 <div class="button-box">
   <el-button size="small" type="primary" @click="submit">保存</el-button>
   <el-button size="small" @click="reset">重置</el-button>
 </div>
```
</template> <script> export default { name: "PaginationPage", data() { return { // 分页信息（默认12条，具体可根据项目调用接口） total: 12, pageNum: 1, pageSize: 10, // 选中的id列表 ids: [], // 列表 list: [ { id: "0001", date: "2016-05-02", name: "王小虎", address: "上海市普陀区金沙江路 1518 弄", flag: false, }, { id: "0002", date: "2016-05-04", name: "王小虎", address: "上海市普陀区金沙江路 1517 弄", flag: true, }, { id: "0003", date: "2016-05-01", name: "王小虎", address: "上海市普陀区金沙江路 1519 弄", flag: false, }, { id: "0004", date: "2016-05-03", name: "王小虎", address: "上海市普陀区金沙江路 1516 弄", flag: false, }, { id: "0005", date: "2016-05-03", name: "王小虎", address: "上海市普陀区金沙江路 1516 弄", flag: true, }, { id: "0006", date: "2016-05-03", name: "王小虎", address: "上海市普陀区金沙江路 1516 弄", flag: true, }, { id: "0007", date: "2016-05-03", name: "王小虎", address: "上海市普陀区金沙江路 1516 弄", flag: false, }, { id: "0008", date: "2016-05-03", name: "王小虎", address: "上海市普陀区金沙江路 1516 弄", flag: true, }, { id: "0009", date: "2016-05-03", name: "王小虎", address: "上海市普陀区金沙江路 1516 弄", flag: false, }, { id: "0010", date: "2016-05-03", name: "王小虎", address: "上海市普陀区金沙江路 1516 弄", flag: false, }, { id: "0011", date: "2016-05-03", name: "王小虎", address: "上海市普陀区金沙江路 1516 弄", flag: false, }, { id: "0012", date: "2016-05-03", name: "王小虎", address: "上海市普陀区金沙江路 1516 弄", flag: true, }, ], }; }, created() { // 默认选中 this.defalutHandle() }, methods: { // 默认选中 defalutHandle() { this.$nextTick(() => { this.list.forEach((row) => { if (row.flag) { this.$refs.table.toggleRowSelection(row); } }); }); }, // 单击选中行数据 clickRow(row) { this.$refs.table.toggleRowSelection(row); }, // 多选框选中数据 handleSelectionChange(selection) { this.ids = selection.map((item) => item.id); console.log(this.ids, '选中的列表的id所组成的数组') }, // 保存选中的数据编号 getRowKey(row) { return row.id; },
```
 // 分页相关
 handleSizeChange(val) {
   console.log(`每页 ${val} 条`);
   this.pageSize = val;
 },
 handleCurrentChange(val) {
   console.log(`当前页: ${val}`);
   this.pageNum = val;
 },

 //保存
 submit() {
   console.log(this.ids, '选中的列表的id所组成的数组')
 },
 //重置
 reset() {
   // 清除复选框
   this.$refs.table.clearSelection()
 },
```
