Vue3 + ElementPlus动态合并数据相同的单元格（超级详细版）

最近的新项目有个需求需要合并单元列表。ElementPlus 的 Table 提供了合并行或列的方法，可以参考一下https://element-plus.org/zh-CN/component/table.html

但项目中，后台数据返回格式和指定合并是动态且没有规律的，Element 的示例过于简单，因此记录下来，大家可以参考一下！

 后台返回的数据结构

代码详解

实操中，需要合并的代码通常就是 list_cnt 数据需要进行合并，因为后台返回的格式都是Data 数据中包裹着 list_cnt 数据，这种格式看起来也是比较清晰。由 Element 文档可知：el-table 组件主要靠 :span-method 方法实现合并。

代码中会有一些注释，根据个人需求可以进行参考，此需求也涉及到按钮操作的，如果没有次需求可以忽略不看。

以上就是列表的合并单元格，如果对你有帮助，麻烦点个赞呗~
