java – 在Excel文件中附加数据
作者:互联网
我正在尝试编写一个程序,将数据附加到Java中的Excel文件中.我达到了以下代码.但它会重写Excel文件中的内容,而不是附加到它.请帮我完成这个.
public class jExcel
{
static WritableWorkbook workbook;
public static void main(String args[])throws Exception
{
workbook = Workbook.createWorkbook((new File("D:\\0077\\my2.xls")));
WritableSheet sheet = workbook.createSheet("First Sheett",1);
Label label = new Label(5,2,"ssssssssss");
sheet.addCell(label);
workbook.write();
workbook.close();
}
}
解决方法:
//写入XLS
WritableWorkbook workbook = Workbook.createWorkbook(new File("D:\\output.xls"));
WritableSheet sheet = workbook.createSheet("First Sheet", 0);
Label label = new Label(0, 2, "A label record");
sheet.addCell(label);
workbook.write();
workbook.close();
//MODIFY XLS
Workbook workbook1 = Workbook.getWorkbook(new File("D:\\output.xls"));
WritableWorkbook copy = Workbook.createWorkbook(new File("D:\\output.xls"), workbook1);
WritableSheet sheet2 = copy.getSheet(0);
//WritableCell cell = sheet2.getWritableCell(5, 2);
copy.write();
copy.close();
