org.apache.poi對更高excel2003文檔的操作
1.導入jar包
dom4j-20040902.021138.jar
ooxml-schemas-1.1.jar
poi-3.9.jar
poi-ooxml-3.9.jar
xmlbeans-2.5.0.jar
2.范例代碼
[java]
package xls;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
import org.apache.poi.ss.util.WorkbookUtil;
