我正在使用apache-poi生成excel文件。我需要使第4列为只读,其余2列将可由用户编辑。
我正在使用XSSFCellStyle
实现此目的,但对我来说不起作用。
整个代码是:
Map<String, XSSFCellStyle> styles = new HashMap<String, XSSFCellStyle>();
XSSFCellStyle style5 = wb.createCellStyle();
XSSFFont headerFont = wb.createFont();
headerFont.setBold(true);
style5.setFillForegroundColor(IndexedColors.GREY_25_PERCENT.getIndex());
style5.setFillPattern(XSSFCellStyle.SOLID_FOREGROUND);
style5.setFont(headerFont);
style5.setLocked(true); // this line does not get executed.
styles.put("header", style5);
最佳答案
您必须保护整个工作表并解锁应可编辑的单元格:
String file = "c:\\poitest.xlsx";
FileOutputStream outputStream = new FileOutputStream(file);
Workbook wb = new XSSFWorkbook();
CellStyle unlockedCellStyle = wb.createCellStyle();
unlockedCellStyle.setLocked(false);
Sheet sheet = wb.createSheet();
sheet.protectSheet("password");
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("TEST");
cell.setCellStyle(unlockedCellStyle);
wb.write(outputStream);
outputStream.close();
