前端分页和后端分页就是请求的差异，前端分页的话只请求一次，所以要在render table组件的时候控制下数据

:data="tableData.slice((currentPage-1)*pageSize,currentPage*pageSize)"   //不多解释

再就是设置分页器total等于table数据的长度

:total="tableData.length"

点击分页器的操作

methods: {
        handleSizeChange(val) {
            console.log(`每页 ${val} 条`);
            this.currentPage = 1;
            this.pageSize = val;
        },
        handleCurrentChange(val) {
            console.log(`当前页: ${val}`);
            this.currentPage = val;
        }
    }

千言万语不如上个demo~

<template>
    <div>
        <el-table :data="tableData.slice((currentPage-1)*pageSize,currentPage*pageSize)" style="width: 100%">
            <el-table-column prop="date" label="日期" width="180">
            </el-table-column>
            <el-table-column prop="name" label="姓名" width="180">
            </el-table-column>
            <el-table-column prop="address" label="地址">
            </el-table-column>
        </el-table>
        <!-- 分页器 -->
        <div class="block" style="margin-top:15px;">
            <el-pagination align='center' @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="currentPage" :page-sizes="[1,5,10,20]" :page-size="pageSize" layout="total, sizes, prev, pager, next, jumper" :total="tableData.length">
            </el-pagination>
        </div>
    </div>

</template>
