不同页面的重复标题不一样

GcExcel允许PDF文件不同页面的重复标题不一样。当PDF文件的每一页上有不同的信息，并且希望PDF文件每一页展示不同的标题时，此功能非常有用。

要为PDF文件中的不同页面配置不同的标题，可以使用setTitleRowStart()方法、setTitleRowEnd()方法和RepeatSetting类的其他方法。完成后，只需创建PrintManager类的实例，使用paginate()方法获取默认分页信息，最后使用savePageInfosToPDF()方法保存并应用设置。

代码用例

请参阅以下示例代码，以便在导出为PDF文件时导出不同页面上的不同标题。

// Initialize workbook
Workbook workbook = new Workbook();
        
// Open Excel file
workbook.open("MultipleHeaders.xlsx");
        
// Fetch default worksheet
IWorksheet worksheet = workbook.getWorksheets().get(0);
List repeatSettings = new ArrayList();

// The title rows of the "B2:F87" is "$2:$2"
RepeatSetting repeatSetting = new RepeatSetting();
repeatSetting.setTitleRowStart(1);
repeatSetting.setTitleRowEnd(1);
repeatSetting.setRange(worksheet.getRange("B2:F87"));
repeatSettings.add(repeatSetting);

// The title rows of the "B89:F146" is "$89:$89"
RepeatSetting repeatSetting2 = new RepeatSetting();
repeatSetting2.setTitleRowStart(88);
repeatSetting2.setTitleRowEnd(88);
repeatSetting2.setRange(worksheet.getRange("B89:F146"));
repeatSettings.add(repeatSetting2);

// Create an instance of the PrintManager class 
PrintManager printManager = new PrintManager();
worksheet.getPageSetup().setRightMargin(10);

// Get the pagination information of the worksheet
List pages = 
printManager.paginate(worksheet, null, repeatSettings);

// Save the modified pages into pdf file
printManager.savePageInfosToPDF("ManageHeadersOnDifferentPages.pdf", pages);
