我有代码，它读取XML文件并显示。我能够在td中为单元格的内容大小，但是如何更改动态创建td单元格的文本的大小。这是代码。

代码：

public class ticketcount {

    public static void main(String[] args) throws IOException {
        List<ticket> ticketList = new ArrayList<ticket>();
        String content = "";
        String content1 ="<HTML><HEAD></HEAD><TABLE border=3>";

            DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
            Document doc = dBuilder.parse(fXmlFile);
            doc.getDocumentElement().normalize();
            NodeList ticketNodeList = doc.getElementsByTagName("ticket");
            for (int temp = 0; temp < ticketNodeList.getLength(); temp++) {
                Node varNode = ticketNodeList.item(temp);
                if (varNode.getNodeType() == Node.ELEMENT_NODE) {
                    Element eElement = (Element) varNode;
