String filename = "excel名字.xls";
res.setHeader("Content-Type", "application/vnd.ms-excel");
res.setHeader("ContentDisposition", "attachment;filename="
+ new String(filename.getBytes("MS932"), "ISO-8859-1"));
调用一个方法，输出要输出的值,hm是个map
outExcel(hm, res.getOutputStream());
别看下面的方法代码多，其实有用的就几行，主要就是控制e799bee5baa6e78988e69d83363row和cell，设置单元格样式，赋值。

比如第一行第一列到第4列合并，那么你合并后的编号就还是第一行第一列，就是给第一行第一列赋值就可以了
源码贴出来，我来帮你改。原因应该是你没把 合并后的单元格赋值导致的。看看poi的api文档。
如下：e68a847a686964616f365
public static String do_post(String url, List<NameValuePair> name_value_pair) throws IOException {
String body = "{}";
DefaultHttpClient httpclient = new DefaultHttpClient();
try {
HttpPost httpost = new HttpPost(url);
httpost.setEntity(new UrlEncodedFormEntity(name_value_pair, StandardCharsets.UTF_8));
HttpResponse response = httpclient.execute(httpost);
HttpEntity entity = response.getEntity();
body = EntityUtils.toString(entity);
} finally {
httpclient.getConnectionManager().shutdown();
}
return body;
}
public static String do_get(String url) throws ClientProtocolException, IOException {
String body = "{}";
DefaultHttpClient httpclient = new DefaultHttpClient();
try {
HttpGet httpget = new HttpGet(url);
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
body = EntityUtils.toString(entity);
} finally {
httpclient.getConnectionManager().shutdown();
}
return body;
}
