使用iText设置标题行的格式

使用iText设置标题行的格式

您的要求在我们的教学视频中进行了详细说明，更具体地说是在United
States
示例中。在此示例中，我们获取一个包含美国不同州的CSV文件：united_states.csv

name;abbr;capital;most populous city;population;square miles;time zone 1;time zone 2;dstALABAMA;AL;Montgomery;Birmingham;4,708,708;52,423;CST (UTC-6);EST (UTC-5);YESALASKA;AK;Juneau;Anchorage;698,473;656,425;AKST (UTC-09) ;HST (UTC-10) ;YESARIZONA;AZ;Phoenix;Phoenix;6,595,778;114,006;MT (UTC-07); ;NOARKANSAS;AR;Little Rock;Little Rock;2,889,450;53,182;CST (UTC-6); ;YESCALIFORNIA;CA;Sacramento;Los Angeles;36,961,664;163,707;PT (UTC-8); ;YES

然后将它们解析为带有重复标头的PDF：united_states.pdf

唯一的区别是，您希望标题中的文本为粗体。这只需要对代码进行最小的更改：

public void createPdf(String dest) throws IOException, documentException {    document document = new document(PageSize.A4.rotate());    PdfWriter.getInstance(document, new FileOutputStream(dest));    document.open();    PdfPTable table = new PdfPTable(9);    table.setWidthPercentage(100);    table.setWidths(new int[]{4, 1, 3, 4, 3, 3, 3, 3, 1});    BufferedReader br = new BufferedReader(new FileReader(DATA));    String line = br.readLine();    process(table, line, new Font(FontFamily.HELVETICA, 16, Font.BOLD));    table.setHeaderRows(1);    while ((line = br.readLine()) != null) {        process(table, line, new Font(FontFamily.HELVETICA, 12));    }    br.close();    document.add(table);    document.close();}public void process(PdfPTable table, String line, Font font) {    StringTokenizer tokenizer = new StringTokenizer(line, ";");    while (tokenizer.hasMoreTokens()) {        table.addCell(new Phrase(tokenizer.nextToken(), font));    }}

仔细看一下

process()

方法的更改方式：它现在接受一个

font

参数，以便我们可以为标题定义更大，更粗体的字体。
