在jExcel API中创build多个工作表
如果一张纸张已满(65536 rows)我需要使用jExcel API在Java中创build多个Excel表格。 假设如果一张纸已满，然后在下一张纸上，它应该开始自动从第一张纸从停止的地方写入。 我只是坚持把逻辑放在一张纸满了的时候dynamic创build。 以下是我迄今为止所做的代码。
public void write() throws IOException, WriteException { File file = new File(inputFile); WorkbookSettings wbSettings = new WorkbookSettings(); wbSettings.setLocale(new Locale("en", "EN")); WritableWorkbook workbook = Workbook.createWorkbook(file, wbSettings); writingToExcel(workbook); } //Logic to create sheet dyanmically if one is full should be done here I guess? private void writingToExcel(WritableWorkbook workbook) { workbook.createSheet("Report", 0); WritableSheet excelSheet = workbook.getSheet(0); try { createLabel(excelSheet); createContent(excelSheet); } catch (WriteException e) { e.printStackTrace(); } finally { try { workbook.write(); workbook.close(); } catch (IOException e) { e.printStackTrace(); } catch (WriteException e) { e.printStackTrace(); } } } private void createLabel(WritableSheet sheet) throws WriteException { WritableFont times10pt = new WritableFont(WritableFont.TIMES, 10); times = new WritableCellFormat(times10pt); times.setWrap(true); WritableFont times10ptBoldUnderline = new WritableFont(WritableFont.TIMES, 10, WritableFont.BOLD, false,UnderlineStyle.SINGLE); timesBoldUnderline = new WritableCellFormat(times10ptBoldUnderline); timesBoldUnderline.setWrap(true); CellView cv = new CellView(); cv.setFormat(times); cv.setFormat(timesBoldUnderline); cv.setAutosize(true); // Write a few headers addCaption(sheet, 0, 0, "Header 1"); addCaption(sheet, 1, 0, "This is another header"); } private void createContent(WritableSheet sheet) throws WriteException, RowsExceededException { for (int i = 1; i < 70000; i++) { addNumber(sheet, 0, i, i + 10); addNumber(sheet, 1, i, i * i); } } private void addCaption(WritableSheet sheet, int column, int row, String s) throws RowsExceededException, WriteException { Label label; label = new Label(column, row, s, timesBoldUnderline); sheet.addCell(label); } private void addNumber(WritableSheet sheet, int column, int row, Integer integer) throws WriteException, RowsExceededException { Number number; number = new Number(column, row, integer, times); sheet.addCell(number); }
我不知道如何在我的代码中添加这个逻辑。
任何build议将有很大的帮助？
或者在任何情况下，任何人都可以提供一个简单的例子，如果一张纸满了，它应该开始自动写入不同的纸张（第二张）？
我对以下两种方法进行了修改：
private void writingToExcel(WritableWorkbook workbook) { try { // don't create a sheet now, instead, pass it in the workbook createContent(workbook); } catch (WriteException e) { e.printStackTrace(); } finally { try { workbook.write(); workbook.close(); } catch (IOException e) { e.printStackTrace(); } catch (WriteException e) { e.printStackTrace(); } } } // instead of taking a sheet, take a workbook because we cannot ensure if the sheet can fit all the content at this point private void createContent(WritableWorkbook workbook) throws WriteException { int excelSheetIndex = 0; int rowIndex = 0; WritableSheet excelSheet = null; for (int i = 1; i < 70000; i++) { // if the sheet has hit the cap, then create a new sheet, new label row and reset the row count if (excelSheet == null || excelSheet.getRows() == 65536) { excelSheet = workbook.createSheet("Report " + excelSheetIndex, excelSheetIndex++); createLabel(excelSheet); rowIndex = 0; } // instead of using i for row, use rowIndex addNumber(excelSheet, 0, rowIndex, i + 10); addNumber(excelSheet, 1, rowIndex, i * i); // increment the sheet row rowIndex++; } }
