erp element-plus的可编辑table表格组件基础封装

封装

思路参考:封装Vue Element的可编辑table表格组件

代码: github.com/lyxxxh/erp-table-form
erp 表格最基础的封装,根据公司项目来完善。

实际情况复杂很多,就连 el-select 都需要重写(需求问题)。

我司的效果图:

环境

// element-plus-vite-starter = element-plus+vite+vue3集成
git clone https://github.com/element-plus/element-plus-vite-starter

// install
npm i

// start
npm run dev
