Apache POI锁定单元格但允许列调整大小-Java 学习之路

我通过 Apache POI XSSF 创建一个Excel文件，然后我用密码锁定工作表，这样用户就可以调整列的大小，这样他既不能更改也不能调整列的大小以读取所有单元格的值 . 即使工作表受到保护，是否可以允许列调整大小？这是我的配置

workbook = new XSSFWorkbook();
sheet = workbook.createSheet("Sheet1");
sheet.protectSheet("passwordExcel"); 
unlockedNumericStyle = workbook.createCellStyle(); 
unlockedNumericStyle.setLocked(false);
// Format cell for date
dateStyle = workbook.createCellStyle();
CreationHelper createHelper = workbook.getCreationHelper();
dateStyle.setDataFormat(createHelper.createDataFormat().getFormat("dd/mm/yyyy"));
sheet.autoSizeColumn(1);

我读到 lockFormatCell() 但我不明白它是否可以帮助我 . 谢谢

为了能够在工作表受到保护时调整列大小，您需要将XSSFSheet.lockFormatColumns设置为 false .

完整的例子：

import java.io.FileOutputStream;

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.*;

public class CreateExcelXSSFProtectedSheet {

 public static void main(String[] args) throws Exception {

  Workbook workbook = new XSSFWorkbook();

  CreationHelper createHelper = workbook.getCreationHelper();

  CellStyle unlockedNumericStyle = workbook.createCellStyle();
  unlockedNumericStyle.setDataFormat(createHelper.createDataFormat().getFormat("$#,##0.00_);[Red]($#,##0.00)"));
  unlockedNumericStyle.setLocked(false);

  CellStyle dateStyle = workbook.createCellStyle();
  dateStyle.setDataFormat(createHelper.createDataFormat().getFormat("dd/mm/yyyy"));

  Sheet sheet = workbook.createSheet();

  Row row = sheet.createRow(0);
  Cell cell = row.createCell(1);
  cell.setCellValue("some data");

  row = sheet.createRow(1);
  cell = row.createCell(1);
  cell.setCellValue(-123456789.0123456);
  cell.setCellStyle(unlockedNumericStyle);

  row = sheet.createRow(2);
  cell = row.createCell(1);
  cell.setCellValue(new java.util.Date());
  cell.setCellStyle(dateStyle);

  ((XSSFSheet)sheet).lockFormatColumns(false);

  sheet.protectSheet("passwordExcel"); 

  sheet.autoSizeColumn(1);

  workbook.write(new FileOutputStream("CreateExcelXSSFProtectedSheet.xlsx"));
  workbook.close();

 }

}
