java - 使用 POI 从 Excel 工作表的下一行获取值

Question

我正在使用 Apache POI 读取 Excel 文档。如果当前为空，我想从下一行获取单元格值。例如，从第一行获取所有非空单元格值，对于空单元格:移动到下一行并获取值。这是我用来读取 Excel 文档的代码

                //every sheet has rows, iterate over them
                Iterator<Row> rowIterator = sheet.iterator();

                if (rowIterator.hasNext())
                    rowIterator.next();

                while (rowIterator.hasNext()) 
                {

                    String libelle="";
                    .....

                    //Get the row object
                    Row row = rowIterator.next();

                    //Every row has columns, get the column iterator and iterate over them
                    Iterator<Cell> cellIterator = row.cellIterator();

                    while (cellIterator.hasNext()) 
                    {
                        //Get the Cell object
                        Cell cell = cellIterator.next();

                        //check the cell type and process accordingly
                        //2nd column

                        switch(cell.getCellType()){
                        case Cell.CELL_TYPE_STRING:

                            ......
                            if (row.getCell(5) == null)
                            {
                               System.out.println("Cell is Empty in Column:" );

                            } else if (row.getCell(5).getCellType() == HSSFCell.CELL_TYPE_STRING)
                            {
                            libelle= row.getCell(5).getStringCellValue().trim();
                            }

Answer 1

您可以使用Sheet.getRow(int rownumber)来获取具有特定编号的行。您可以通过 Row.getRowNum() 获取当前行号，通过 Cell.getColumnIndex() 获取单元格索引。

因此，下一行单元格的值将是

Row nextRow = sheet.getRow(row.getRowNum() + 1);
if (nextRow != null)
    String value = nextRow.getCell(curCel.getColumnIndex(), Row.CREATE_NULL_AS_BLANK).getStringCellValue();
