部分代码如下(POI的版本为3.2)

public void insertRow() throws IOException {

POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream("workbook.xls"));

HSSFWorkbook wb = new HSSFWorkbook(fs);

HSSFSheet sheet = wb.getSheet("new sheet");

int starRow = 4;

int rows = 5;

sheet.shiftRows(starRow + 1, sheet.getLastRowNum(), rows,true,false);

//Parameters:

//startRow - the row to start shifting

//endRow - the row to end shifting

//n - the number of rows to shift

//copyRowHeight - whether to copy the row height during the shift

//resetOriginalRowHeight - whether to set the original row's height to the default

starRow = starRow - 1;

for (int i = 0; i < rows; i++) {

HSSFRow sourceRow = null;

HSSFRow targetRow = null;

HSSFCell sourceCell = null;

HSSFCell targetCell = null;

short m;

starRow = starRow + 1;

sourceRow = sheet.getRow(starRow);

targetRow = sheet.createRow(starRow + 1);

targetRow.setHeight(sourceRow.getHeight());

for (m = sourceRow.getFirstCellNum(); m < sourceRow.getLastCellNum(); m++) {

sourceCell = sourceRow.getCell(m);

targetCell = targetRow.createCell(m);

//targetCell.setEncoding(sourceCell.getEncoding());

targetCell.setCellStyle(sourceCell.getCellStyle());

targetCell.setCellType(sourceCell.getCellType());

targetCell.setCellValue(i);//設置值

}

}

FileOutputStream fileOut = new FileOutputStream("workbook.xls");

wb.write(fileOut);

fileOut.close();

}
