宏文件加载不了图标效果
又是一个网上没啥资源教程的问题 😦 特此写一个工具类帮助大家 😃
业务需求需要导出的Excel带有宏文件内容，类似于：👇👇👇

数据导出后自由修改折线图要联动

准备

首先要实现此功能需要有一个宏模板，结合你自己期望值来制作一个宏模板。我上传自己的供大家参考，文件后缀是.xlsm

提取码:mc5p

注意：创建或者打开新的宏文件一定得启用内容，不启用看不到宏文件效果
在这里插入图片描述

明确

其实化繁为简，我们只要在模板中传入数据，就可以制作出宏文件

开发

数据格式参考

首先明确报表数据格式，需要X,Y 轴，表头，折线样式…
在线JSON解析可用于显示下列数据
 echarts报表看不懂的参数去这随便点开一个看一下就知道了
