u"""把「从原理图导入变更」对话框的变更表**按 DOM 行结构**读出来（不是 innerText 拼接）。

    /c/Python314/python .claude/p1_import_rows2.py [--board2]

## 为什么要再写一个

`pcb1_import.py --probe` 读的是滚动容器的 `innerText`。那样拿到的是一大坨文本，
**表头行（位号）和明细行（动作/旧值/新值）之间的归属关系是靠换行猜的**，
一旦表格是虚拟滚动 / 分列渲染，就会把 A 的表头和 B 的明细拼到一起 ——
2026-09-08 就是这么读出一份「整个风扇块按位号错位一格」的吓人清单，
而 `pcb1_import.py --verify`（PCB 元件表 vs 原理图 BOM）说 301 个位号全对、
封装只差 J1 一处。两者必有一个是假的。

这里改成逐 `<tr>` 读、每行自己带着单元格，谁属于谁不用猜。
每行还带上 `rowTop`，行序一目了然。
