由于策划计算的表格结构和程序实际使用的数据表结构不一定一致，因此有时候经常需要做数据转化。把策划自己的表格转成程序需要的格式，然后再导入数据库。这次也是策划有个表，里面有多个字段分别表示多个属性，但是程序考虑到通用，不想一个属性增加一个字段，因此想用一个字段，然后采用JSON格式来表示所有属性。
因此，帮策划写了个VBA实现多个字段合并成JSON的。这个VBA可以通过Ctrl表格来配置：
源表名：策划表的名字
目标表名：程序表的名字
字段映射：程序表的字段名对应策划表的字段名。目前支持字段合并（即把策划表里面的多个字段使用JSON合并成程序表需要的一个字段）。字段映射的行数和程序表的字段数量一样。

上面Ctrl表的配置表示：
把策划表Source里面的mechaId列的数据复制到程序表的mechaId列；
把策划表Source里面的quality列的数据复制到程序表的quality列；
把策划表的

这个是程序的数据表（通过点击控制页的按钮生成的）
写这个包括查VBA的资料总共大概花了2个小时，不得不说，VBA的语法真不好看！
勇敢的冷静的理智的去接受失败，有时不但是必要的，而且是很有必要的。
