使用IText将HTML表格转换为PDF格式

Question

public class FontItext {
    public static void main(String[] args) throws IOException, DocumentException {
        com.itextpdf.text.Document document = new com.itextpdf.text.Document(PageSize.A4,55f,30f,30f,30f);
        document.setMarginMirroring(true);
        PdfWriter.getInstance(document, new FileOutputStream("D://AAA.pdf"));
        document.open();       
        BaseFont bf = BaseFont.createFont("D:\\times.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
        Font font = new Font(bf);
        Paragraph _p = new Paragraph();       
        ArrayList htmlObjs = (ArrayList)HTMLWorker.parseToList(new StringReader("<table border=1><tr><td>Test</td><td>Test</td></tr></table>"),
                null);
        for (int k = 0; k < htmlObjs.size(); ++k) {
            ArrayList<Chunk> chunk = (ArrayList<Chunk>)((Paragraph)htmlObjs.get(k)).getChunks();
            for (int l = 0; l < chunk.size(); l++) {
                Font _original_chunk_font = chunk.get(l).getFont();
                Font _newchunk_font = new Font(bf);
                _newchunk_font.setFamily(_original_chunk_font.getFamilyname());
                _newchunk_font.setStyle(_original_chunk_font.getStyle());
                _newchunk_font.setSize(_original_chunk_font.getSize());
                _newchunk_font.setColor(_original_chunk_font.getColor());
                chunk.get(l).setFont(_newchunk_font);
            }
            _p.add((Element)htmlObjs.get(k));

            document.add((Element)htmlObjs.get(k));

        } 

        document.close();
    }
}

错误......

Exception in thread "main" java.lang.ClassCastException: com.itextpdf.text.pdf.PdfPTable cannot be cast to com.itextpdf.text.Paragraph
    at Font.FontItext.main(FontItext.java:46)

嘿伙计帮助我......

我对IText没有那么多经验，但例外说：

取代：

ArrayList<Chunk> chunk = (ArrayList<Chunk>)((Paragraph)htmlObjs.get(k)).getChunks();

通过

ArrayList<Chunk> chunk = (ArrayList<Chunk>)((PdfPTable)htmlObjs.get(k)).getChunks();
