|

|
||||
为了满足 **PRD V2.1** 中“即时反馈”、“撤销重做”以及复杂的“长宽转换”需求，工具 C 采用 **"Local-First" (本地优先)** 架构。
|
||||
|
||||
核心策略：
|
||||
|
||||
1. **数据驻留：** 数据加载后主要存储在浏览器的 **IndexedDB (Dexie.js)** 和 **内存 (Zustand)** 中。
|
||||
2. **计算下放：** 复杂的计算逻辑（如 Pivot、公式解析）下放至 **Web Worker**，避免阻塞 UI 主线程。

* valueCols: 值列名数组 (e.g., \['wbc', 'bmi'\]) \- 确定“填充值”

1. **预检查 (Guard):** 计算 Unique(pivotKeyCol).length \* valueCols.length。如果生成的潜在列数 \> 1000，抛出错误“生成的列数过多，请先筛选数据”。

2. **分组 (Grouping):** 使用 \_.groupBy(data, indexCol) 按主键分组。
|
||||
3. **转换 (Transformation):** 遍历每组数据：
|
||||
* 创建一个新行对象，保留主键。
|
||||
* 遍历该组的每一条记录，获取 pivotKeyCol 的值（例如 "2023-01-01"）。
|

* 遍历 valueCols，将值映射为 ValueCol\_PivotKey (例如 "wbc\_2023-01-01")。
