spreadjs保存在线excel到服务器指定位置后格式和原excel格式不一致

收藏

导入excel，导入成功后，点击保存，保存到

然后打开保存位置的excel和之前导入的对比，发现保存的和原来的格式不一致

现在想要实现的就是，保存的能和原先的格式保持一致

下图是保存后打开的样式，与最上面导入在线预览的样式不一致

这是保存事件的代码：

Exporter excelExporter = new Exporter(this.HiddenField2.Value);
MemoryStream stream = new MemoryStream();
excelExporter.SaveExcel(stream);
byte[] bts = new byte[stream.Length];
stream.Read(bts, 0, (int)stream.Length);
//FileStream fs = new FileStream("D:\\test.xlsx", FileMode.OpenOrCreate);
//BinaryWriter w = new BinaryWriter(fs);
//w.Write(stream.ToArray());
//fs.Close();
//stream.Close();
string url = "/upload/预算价格计算-20160722142227-钢构材料价格表.xlsx";
if (url != null && url != "")
{
FileStream fs = new FileStream(Server.MapPath(url), FileMode.OpenOrCreate);
BinaryWriter w = new BinaryWriter(fs);
w.Write(stream.ToArray());
fs.Close();
stream.Close();
Page.RegisterStartupScript("string key", "<script>alert('操作成功！');window.close();</script>"); ;
}
