I am using Apache POI to generate Exccel Templete which my clients could download, add values and upload back.
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。
I would like to set the cell values non editable so that the template headers could not be edited.
我想将单元格值设置为不可编辑，以便无法编辑模板标题。
I tried this code but it does not work,
我试过这段代码，但它不起作用，
cell.getCellStyle().setLocked(true)
I also read that locking the excel sheet and then allowing the columns to setlocked(false) would work but I am not sure how many columns will be filled by client, so I want is all other columns t be edited except the one which I filled dynamically with Apache POI.
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。
I hope my query is clear to understand.
我希望我的查询清楚明白。

Try the following code, it may solve your problem:
尝试以下代码，它可以解决您的问题：
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.

I don't recall how well this works -- for example, I think that the client can unprotect the sheet using the menu -- but you do need to protect the sheet via something like Sheet.protectSheet("") (no password, but nevertheless a protected sheet.)
我不记得这有多好用 - 例如，我认为客户端可以使用菜单取消对表单的保护 - 但你需要通过Sheet.protectSheet（“”）之类的东西来保护表单（没有密码，但仍然是一张受保护的床单。）
