=== 8. 實作建議 === PDF 表格解析器可以採用分層設計,將擷取、分類、清理、狀態管理、標準化與驗證分開處理。 建議流程如下: # 從 PDF 擷取文字、表格與座標資訊。 # 辨識頁面所屬章節與表格區塊。 # 根據表頭關鍵字判斷 <code>table_type</code>。 # 套用對應的表格結構定義與欄名別名對照表。 # 辨識資料列、父列、子列與接續列。 # 管理跨頁狀態、父列狀態與其他文件層級狀態。 # 將資料轉換為標準化紀錄。 # 加入來源中繼資料。 # 執行迴歸檢查與資料品質檢查。 # 輸出 JSON、CSV 或可直接匯入資料庫的紀錄。 這種設計可以降低個別規則與特定 PDF 版面過度耦合的風險,也能在文件格式改變時,更容易只調整受影響的部分。 [[Category: Tool]] [[Category: PDF]] [[Category: Revised with LLMs]]
