As you have discovered yourself, the main problem you experienced was caused by feeding invalid HTML to XML Worker. I have written a Java example that is equivalent to your (updated) C# example:

public static final String CSS = "th { background-color: #C0C0C0; font-size: 16pt; } "
    + "td { font-size: 10pt; }";
public static final String HTML = "

    
        
                   


        
      
      
      
"
    + ""
    + ""
    + ""
    + "Customer Name Customer's Address  
 XYZ  Bhubaneswar 
 MNP  Cuttack 
";

/**
 * @param file
 * @throws IOException
 * @throws DocumentException
 */
public void createPdf(String file) throws IOException, DocumentException {
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
    document.open();


    CSSResolver cssResolver = new StyleAttrCSSResolver();
    CssFile cssFile = XMLWorkerHelper.getCSS(new ByteArrayInputStream(CSS.getBytes()));
    cssResolver.addCss(cssFile);

    // HTML
    HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
    htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());

    // Pipelines
    PdfWriterPipeline pdf = new PdfWriterPipeline(document, writer);
    HtmlPipeline html = new HtmlPipeline(htmlContext, pdf);
    CssResolverPipeline css = new CssResolverPipeline(cssResolver, html);

    // XML Worker
    XMLWorker worker = new XMLWorker(css, true);
    XMLParser p = new XMLParser(worker);
    p.parse(new ByteArrayInputStream(HTML.getBytes()));
    document.close();
}

Customer Name	Customer's Address
XYZ	Bhubaneswar
MNP	Cuttack



The resulting table looks like this:



You can tweak the values stored in CSS to create a nicer appearance for the table.
