java excel读取一列

Question

我有一列 (B)，我需要获取 B3 和 B20 之间的所有值

这是我的代码

try {
            OPCPackage fs;

            fs =  OPCPackage.open(new File(getFilePath()));

            XSSFWorkbook wb = new XSSFWorkbook(fs);
            XSSFSheet sheet = wb.getSheet("Master column name - Used Car");
            XSSFRow row;
            CellReference cr = new CellReference("B3");

            row = sheet.getRow(4); 
            System.out.println(row);

但正如你所看到的，我得到一个值，我不知道如何获取单元格 B3 的值，直到 B20

请帮忙

您是否尝试过替换此行:

CellReference cr = new CellReference("B3");

与:

AreaReference ar = new AreaReference("B3:B20");

即

AreaReference ar = new AreaReference("B3:B20");

for (cr : ar.getAllReferencedCells()) {
    System.out.print(cr.formatAsString());
    System.out.print(" - ");
}
System.out.println();
