将表格封装成为一个组件：

<element-table
          ref="elementTable"
          :url="url"
          :params="searchParams"
          :columns="columns"
          v-model:currentPage="currentPage"
          @columnClick="columnClick"
        />

引入：

import ElementTable from "./components/common/ElementTable";

挂载：

 components: {
    ElementTable
  },

定义所需要传递的参数：

data(){
 return {
  columns: [
        {
          key: "processName",
          title: "流程名称"
        },
        {
          key: "aliasName",
          title: "流程别名"
        },
        {
          key: "department",
          title: "部门"
        },
        {
          key: "remark",
          title: "备注"
        },
        {
          key: "status",
          title: "状态",
          formatter: (row, key) => {

              return "已发布";
            }

          }
        },
        {

          title: "操作",
