/**
|
||
* 对比脚本：商旅 vs 吉智 金额核对
|
||
*
|
||
* 输入：一个包含「商旅」和「吉智」两个 sheet 的 Excel（即 merge_kaipiao.js 的合并结果）。
|
||
*
|
||
* 逻辑：
|
||
* 1. 商旅 sheet：按「结算账户」聚合，「账单总金额」相加。
|
||
* 2. 吉智 sheet：按「*对账单/项目名称」聚合，「*账单应收总金额」相加。
|
||
* （吉智的「*对账单/项目名称」对应商旅的「结算账户」）
|
||
* 3. 对比两侧同一 key 的金额，找出不同：
|
||
* - 仅商旅有的 key
|
||
* - 仅吉智有的 key
|
||
* - 两侧都有但金额不一致的 key
|
||
*
|
||
* 用法：
|
||
* node compare_kaipiao.js <合并excel路径> [输出结果路径]
|
||
*
|
||
* 例如：
|
||
* node compare_kaipiao.js "团队开票申请表-合并.xlsx" "对比结果.xlsx"
