在excel中复制具有范围的行公式

Question

我正在创建一个应用程序，在该应用程序中我在用户输入一些输入后生成一个 Excel 工作表。 如果用户输入 5 条记录，我将处理初始/第一行（带有公式的单元格），然后在单元格中插入每个值。问题是在处理行之后，公式范围没有被更新，例如。如果初始行是 10th 并且单元格 A 有一个类似 SUM(G10:K10) 的公式，那么在处理完第 10th 行之后strong> 到 11th 公式保持不变，即 SUM(G10:K10) 而不是 SUM(G11:K11)。 谁能帮我解决这个问题。这是代码

HSSFSheet existingSheet = existingWorkBook.getSheetAt(0);
ExcelFile.copyRow(existingWorkBook, existingSheet, startRowColumn - 2, startRowColumn - 1);


public static void copyRow(HSSFWorkbook workbook, HSSFSheet worksheet, int sourceRowNum, int destinationRowNum) {
    // Get the source / new row
    HSSFRow newRow = worksheet.getRow(destinationRowNum);
    HSSFRow sourceRow = worksheet.getRow(sourceRowNum);

    // If the row exist in destination, push down all rows by 1 else create a new row
    if (newRow != null) {
        worksheet.shiftRows(destinationRowNum, worksheet.getLastRowNum(), 1);
    } else {
        newRow = worksheet.createRow(destinationRowNum);
    }

    // Loop through source columns to add to new row
    for (int i = 0; i < sourceRow.getLastCellNum(); i++) {
        // Grab a copy of the old/new cell
        HSSFCell oldCell = sourceRow.getCell(i);
        HSSFCell newCell = newRow.createCell(i);

        // If the old cell is null jump to next cell
        if (oldCell == null) {
            newCell = null;
            continue;
        }

        // Copy style from old cell and apply to new cell
        HSSFCellStyle newCellStyle = workbook.createCellStyle();
        newCellStyle.cloneStyleFrom(oldCell.getCellStyle());
        ;
        newCell.setCellStyle(newCellStyle);

        // If there is a cell comment, copy
        if (oldCell.getCellComment() != null) {
            newCell.setCellComment(oldCell.getCellComment());
        }

        // If there is a cell hyperlink, copy
        if (oldCell.getHyperlink() != null) {
            newCell.setHyperlink(oldCell.getHyperlink());
        }

        // Set the cell data type
        newCell.setCellType(oldCell.getCellType());

        // Set the cell data value
        switch (oldCell.getCellType()) {
            case Cell.CELL_TYPE_BLANK:
                newCell.setCellValue(oldCell.getStringCellValue());
                break;
            case Cell.CELL_TYPE_BOOLEAN:
                newCell.setCellValue(oldCell.getBooleanCellValue());
                break;
            case Cell.CELL_TYPE_ERROR:
                newCell.setCellErrorValue(oldCell.getErrorCellValue());
                break;
            case Cell.CELL_TYPE_FORMULA:
                newCell.setCellFormula(oldCell.getCellFormula());
                break;
            case Cell.CELL_TYPE_NUMERIC:
                newCell.setCellValue(oldCell.getNumericCellValue());
                break;
            case Cell.CELL_TYPE_STRING:
                newCell.setCellValue(oldCell.getRichStringCellValue());
                break;
        }
    }

    // If there are are any merged regions in the source row, copy to new row
    for (int i = 0; i < worksheet.getNumMergedRegions(); i++) {
        CellRangeAddress cellRangeAddress = worksheet.getMergedRegion(i);
        if (cellRangeAddress.getFirstRow() == sourceRow.getRowNum()) {
            CellRangeAddress newCellRangeAddress = new CellRangeAddress(newRow.getRowNum(),
                    (newRow.getRowNum() + (cellRangeAddress.getLastRow() - cellRangeAddress.getFirstRow())), cellRangeAddress.getFirstColumn(),
                    cellRangeAddress.getLastColumn());
            worksheet.addMergedRegion(newCellRangeAddress);
        }
    }


}

处理一行后，下面是插入单元格值的代码。

Iterator rowIter = existingSheet.rowIterator();
while (rowIter.hasNext()) {
            HSSFRow oldRow = (HSSFRow) rowIter.next();
            if (rowCounterOld >= startRowColumn - 2 && !isRecordInserted) {
                if (configFieldsIndexes != null && configFieldsIndexes.size() > 0) {
                    for (Map.Entry entry : configFieldsIndexes.entrySet()) {
                        for (Map.Entry<String, String> entry1 : valueMap.entrySet()) {
                            if (((Map.Entry) entry1).getKey().toString().equalsIgnoreCase(entry.getKey().toString())) {
                                try {
                                    float value = Float.valueOf(entry1.getValue());
                                    oldRow.getCell(ExcelFile.getExcelColumnNumber(entry.getValue().toString())).setCellValue(value);
                                } catch (NumberFormatException e) {
                                    e.printStackTrace();
                                    oldRow.getCell(ExcelFile.getExcelColumnNumber(entry.getValue().toString())).setCellValue(entry1.getValue());
                                }

                                break;
                            }
                        }

                    }
                    isRecordInserted = true;
                    lastInsertedRow = rowCounterOld;

                }
            }
            rowCounterOld++;
            //rowCounterNew++;
        }

如果A10中有初始公式，那么简单使用VBACopy方法填充A11：

Sub KopyFormula()
    Dim A10 As Range, A11 As Range

    Set A10 = Range("A10")
    Set A11 = Range("A11")

    A10.Copy A11
End Sub
