PDF/UA: Implement Table support in Tagged PDF

Table support was added to Tagged PDF. Use createTableElement() method of ITaggedContent interface to create table. For creating Head, Body and Foot for table use createTHead(), createTBody() and createTFoot() methods of TableElement object. Abstract class TableRowCollectionElement is base for TableTHeadElement, TableTBodyElement and TableTFootElement classes.Method TableRowCollectionElement.createTR() creates the row for corresponded object. Table row object belong to TableTRElement calss. Methods TableTRElement.createTH() and TableTRElement.createTD() creates the row’s cell for corresponded row. You can also verify PDF/UA compliance of the created document. Code snippet below show how to use this functionality.

 Document document = new Document();

ITaggedContent taggedContent = document.getTaggedContent();

taggedContent.setTitle("Table example - THead, TBody, TFoot; Summary");

taggedContent.setLanguage("en-US");

StructureElement rootElement = taggedContent.getRootElement();

TableElement tableElement = taggedContent.createTableElement();

rootElement.appendChild(tableElement);

TableTHeadElement tableTHeadElement = tableElement.createTHead();

TableTBodyElement tableTBodyElement = tableElement.createTBody();

TableTFootElement tableTFootElement = tableElement.createTFoot();

int rowCount = 7;

int colCount = 3;

int rowIndex;

int colIndex;

TableTRElement headTrElement = tableTHeadElement.createTR();

headTrElement.setAlternativeText("Head Row");

for (colIndex = 0; colIndex < colCount; colIndex++)

{

    TableTHElement thElement = headTrElement.createTH();

    thElement.setText("Head Cell [head row, "+colIndex+"  ]");

}

for (rowIndex = 0; rowIndex < rowCount; rowIndex++)

{

    TableTRElement trElement = tableTBodyElement.createTR();

    trElement.setAlternativeText("Row "+rowIndex);

    for (colIndex = 0; colIndex < colCount; colIndex++)

    {

        TableTDElement tdElement = trElement.createTD();

        tdElement.setText("Cell ["+rowIndex+", "+colIndex+"]");

    }

}

TableTRElement footTrElement = tableTFootElement.createTR();

footTrElement.setAlternativeText("Foot Row");

for (colIndex = 0; colIndex < colCount; colIndex++)

{

    TableTDElement tdElement = footTrElement.createTD();

    tdElement.setText("Foot Cell [foot row, "+colIndex+"]");

}

StructureAttributes tableAttributes = tableElement.getAttributes().getAttributes(AttributeOwnerStandard.Table);

StructureAttribute summaryAttribute = new StructureAttribute(AttributeKey.Summary);

summaryAttribute.setStringValue("The summary text for table");

tableAttributes.setAttribute(summaryAttribute);

// Save document

document.save(dataDir+"TaggedTable_"+version+".pdf");

boolean isPdfUaCompliance = document.validate(new ByteArrayOutputStream(), PdfFormat.PDF_UA_1);

System.out.println("PDF/UA compliance: "+ isPdfUaCompliance);
