用javaPOI包的方法获取excel中的行列号

现在需要用java的POI包的方法获取到excel某一个单元格的坐标，也就是他的行号 和 列号 ，比如：
A B C D
1 a f v s
2 s e d m
我现在确定了 f的位置，用什么方法可以得到他的列号，也就是如何得到“B”。poi里面提供这种方法了吗？

Answer 3

POIFSFileSystem fs=new POIFSFileSystem(new FileInputStream("d:\\test.xls"));
HSSFWorkbook wb = new HSSFWorkbook(fs);
HSSFSheet sheet = wb.getSheetAt(0);
HSSFRow row = sheet.getRow(0);
//f列索引位置
int index = 1;
HSSFCell cell = row.getCell((short) index);
String msg = cell.getStringCellValue();
