Apache poi HSSF 返回不正确的物理行数

Question

I am working on user given Excel file (.xls) and using Apache poi HSSF to read the worksheet. The Excel contains 16 rows physically.

• 13th row is empty.
• 14th row has data
• 15th row is empty
• 16th row has data

In this case, worksheet.getPhysicalRows() returns 13.
While, worksheet.getLastRowNum() returns 16.

And note if I deleted 13th row, getPhysicalRows() returns 14.
if I also deleted 16th row, getPhysicalRows() still returns 14.

The last row with valid data is not read at all.

Have you encountered this behaviour with XLS?

Edit: I am not sure if this code can help the question.

 excelDocumentStream = new FileInputStream(new File(xlFilePath));
 POIFSFileSystem fsPOI = new POIFSFileSystem(new BufferedInputStream(excelDocumentStream));
 workbook = new HSSFWorkbook(fsPOI);
 int numOfRows = workSheet.getPhysicalNumberOfRows();
 int lastRow = workSheet.getLastRowNum();

Answer 1

do it like this

int rows = 0;
if(sheet.getPhysicalNumberOfRows()>0)
   rows=sheet.getLastRowNum() - sheet.getFirstRowNum()+1;

Hope this helps!!!
