一个常见的elementUI表格，从后端获取数据并分页及查询

<template>
  <div class="page-container">
    <!--查询工具栏-->

                <kt-button icon="fa fa-search" :label="$t(‘action.search‘)" type="primary" @click="listApp(null)"/>
            </el-form-item>
        </el-form>
    </div>
    <!--内容表格-->

            </template>
        </el-table-column>
    </el-table>
    <!--分页-->
    <div class="toolbar" style="padding:10px;">
        <el-pagination 
          layout="total, prev, pager, next, jumper"
