本次经验内容中将以Java示例展示读取PDF中的表格的方法。这里使用到的主要类、方法及解释如下，供参考：1. PdfDocument Class：Represents a pdf document model.2. PdfDocument. loadFromFile (string filename) Method：Loads a PDF document.3. PdfTableExtractor Class：Represents the PDF table extractor.4. PdfTable Class：Defines a PDF table.5. PdfTableExtractor. extractTable (int pageIndex) Method：Extracts table from page.6. PdfTable.getText(int rowIndex,int columnIndex) Method：Gets Text in cell.7. FileWriter. write() Method：Saves extracted text in table to a .txt file.工具/原料moreIntelliJ IDEA 2018(JDK 1.8.0)PDF 测试文档PDF Jar包：Spire.PDF for Java Version: 4.10.2导入jar1/3分步阅读
