ElTableChen

表格组件：1、集成 el-table 与 el-pagination 组件为一体,可进行前后端分页；2、表格高度自适应；3、表格与卡片两种展现方式；

安装

• 1. 由于组件依赖 element-ui,所以项目需要引入element-ui
• 2. 安装 ElTableChen

     npm i el-table-chen -S

注册

import ElTableChen from "el-table-chen";
Vue.use(ElTableChen, {
  containerId: "app", // 全局配置容器id
  responseFn: function(res) {
    // 全局ajax请求成功后的回调函数，可不配置
    if (res && res.data && Array.isArray(res.data)) {
      this.dataSource = res.data || [];
      this.total = this.dataSource.length;
    } else {
      this.dataSource = res && res.data && res.data.list ? res.data.list : [];
      this.total = res.data.totalCount;
    }
    // 如果数据为空并且当前页码大于1,则页码减一重新获取数据
    this.againGetData();
  }
});

效果图
