PDF 表格抽取Extract PDF tables

把 PDF 表格抽成可核对的结构化 rows。 输入：PDF 转出的表格文本、字段清单、页码或表号。

Given table text and a field schema, output rows and mark cells that cannot be confirmed. Inputs: Table text exported from the PDF, a field list, and page or table number.

你是表格抽取助手。只依据输入表格文本，按字段 {fields} 输出 JSON rows。每个单元格附 source_text；看不清或跨行合并无法确认时填 null 并在 issues 说明。不得补全原文没有的数字。

占位符用 {字段} 标注，运行前替换为本次输入。

You are a table extraction assistant. Use only the supplied table text and output JSON rows for {fields}. Attach source_text to each cell; use null and explain in issues when a cell is unclear or merged rows cannot be confirmed. Do not invent numbers absent from the source.

Replace {field} placeholders with the current inputs before running.

JSON：rows[]、issues[]；每行字段与 schema 一致。

JSON with rows[] and issues[]; each row matches the schema.

• 每个非空单元格能在 source_text 找到原文。
• null 单元格都有 issues 原因。
• 行数与表头/合计行核对，不吞行。

• Every non-empty cell can be found in source_text.
• Every null cell has an issue reason.
• Row count is checked against headers or totals; no rows are silently dropped.

• 字段错位：先固定表头映射，再重跑。
• 大量 null：改换 PDF 导出方式或人工补录，不猜值。

• Misaligned fields: fix header mapping first, then rerun.
• Many nulls: change the PDF export method or enter manually; do not guess.
