Class TableAbsorber


  • public class TableAbsorber
extends Object

    Represents an absorber object of table elements. Performs search and provides access to search results via TableAbsorber.TableList collection. 

     The example demonstrates how to find table on the first PDF document page and replace the text in a table cell.

        // Open document
 Document doc = new Document("D:\\Tests\\input.pdf");
 // Create TableAbsorber object to find tables
 TableAbsorber absorber = new TableAbsorber();
 // Visit first page with absorber
 absorber.visit(doc.getPages().get_Item(1));
 // Get access to first table on page, their first cell and text fragments in it
 TextFragment fragment = absorber.getTableList().get_Item(0).getRowList().get_Item(0).getCellList().get_Item(0)
 .getTextFragments().get_Item(1);
 // Change text of the first text fragment in the cell
 fragment.setText("hi world");
 // Save document
 doc.save("D:\\Tests\\output.pdf");
