POI Excel - 行移动

要将行从顶部移到底部，反之亦然，Apache POI提供了shiftRows()方法来执行行移动。此方法需要开始行，结束行和要移动的行数。

让无涯教程看一个例子来了解整个变速过程。

Apache POI 移位行示例

package poiexample;
import java.io.FileOutputStream;
import java.io.OutputStream;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
public class ShiftRowsExample {
	public static void main(String[] args) {
		try (OutputStream os = new FileOutputStream("Learnfk.xls")) {
			Workbook wb = new HSSFWorkbook();
	            Sheet sheet = wb.createSheet("Sheet");
			Row row     = sheet.createRow(1);
			Row row2    = sheet.createRow(2);
			Cell cell   = row.createCell(1);
			Cell cell2  = row2.createCell(1);
			cell2.setCellValue("Hello, Javaipoint");			
	        sheet.shiftRows(1, 2, -1);
	        wb.write(os);
	    }catch(Exception e) {
	    	System.out.println(e.getMessage());
	    }		
	}
}
