ag-grid-vue列表设置属性:pagination="true"就能开启分页，但是ag-grid-vue列表自带的分页样式不好看，使用el-element-ui的分页既能直接使用它的样式，也能自己快速设置关于分页的size-change和current-page方法，也能设置page-size属性。
首先第一步

一、隐藏ag-grid自带的分页样式

 /* 隐藏ag-grid自带的分页样式 */
.ag-paging-panel{
  display:none;
}

接着写结构，此处使用ag-theme-balham主题，data里面定义表格的一些属性可以看我之前的博客Ag-grid在vue中使用的必要属性

二、搭建ag-grid列表结构

<div>
 <ag-grid-vue
    :selectCol="selectCol"
    :rowHeight="rowHeight"
    :headerHeight="headerHeight"
    :minColWidth="minColWidth"
    class="ag-theme-balham"
    style="height: 400px"
    @gridReady="onGridReady"
    :columnDefs="columnDefs"
    :rowData="rowData"
    cacheBlockSize="0"
    maxBlocksInCache="0"
    :animateRows="true"
    :pagination="true"
    :defaultColDef="defaultColDef"
    :context="context"
    :gridOptions="gridOptions"
  >
  </ag-grid-vue>
  <div class="my_pagination">
    <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page.sync=searchForm.currentPage
      :page-sizes="[20, 50, 100, 200, 300]"
      :page-size=searchForm.pageSize
      layout="total, sizes, prev, pager, next, jumper"
      :total="totalRows"
      background
      >
    </el-pagination>
  </div>
</div>

三、初始化列

四、数据渲染列表

五、设置列表的字段

在没有接口保存到后端的情况下，使用store2保存或者使用本地存储localStorage。

六、定义element-ui分页的方法

 handleSizeChange(val) {
    this.searchForm.pageSize = val;
    // 调接口
  },
  handleCurrentChange(val) {
    this.searchForm.currentPage = val;
    // 调接口
  }

六、完整代码

<template>
  <div>
    <ag-grid-vue
      :selectCol="selectCol"
      :rowHeight="rowHeight"
      :headerHeight="headerHeight"
      :minColWidth="minColWidth"
      class="ag-theme-balham"
      style="height: 400px"
      @gridReady="onGridReady"
      :columnDefs="columnDefs"
      :rowData="rowData"
      cacheBlockSize="0"
      maxBlocksInCache="0"
      :animateRows="true"
      :pagination="true"
      :defaultColDef="defaultColDef"
      :context="context"
      :gridOptions="gridOptions"
    >
    </ag-grid-vue>
    <div class="my_pagination">
      <el-pagination
        @size-change="handleSizeChange"
        @current-change="handleCurrentChange"
        :current-page.sync=searchForm.currentPage
        :page-sizes="[20, 50, 100, 200, 300]"
        :page-size=searchForm.pageSize
        layout="total, sizes, prev, pager, next, jumper"
        :total="totalRows"
        background
        >
      </el-pagination>
    </div>
  </div>
</template>
