Apache POI - Excel写入 - 锁定单个单元格

Question

我正在使用Apache POI生成我的客户可以下载的Exccel Templete,添加值并上传回来.

我想将单元格值设置为不可编辑,以便无法编辑模板标题.

我试过这段代码,但它不起作用,

    cell.getCellStyle().setLocked(true)

我还读到锁定excel表然后允许列setlocked(false)可以工作,但我不确定客户端将填充多少列,所以我想要编辑所有其他列除了我填写的列动态地使用Apache POI.

我希望我的查询清楚明白.

尝试以下代码，它可能会解决您的问题：

HSSFWorkbook workbook = new XSSFWorkbook(); 

// Cell styles. Note the setLocked(true) method call. 
HSSFCellStyle lockedNumericStyle = workbook.createCellStyle(); 
lockedNumericStyle.setAlignment(XSSFCellStyle.ALIGN_RIGHT); 
lockedNumericStyle.setLocked(true); 

HSSFSheet sheet = workbook.createSheet("Protection Test"); 
HSSFRow row = sheet.createRow(0); 
HSSFCell cell = row.createCell(0); 
cell.setCellValue(100); 
cell.setCellStyle(lockedNumericStyle); 

// This line should cause all locked cells to be protected, 
// the user should not be able to change the cells 
// contents. 
sheet.protectSheet("password"); 

The password makes it possible to remove the protection from the sheet and makes it possible then for the locked cells to be modified.
