将 html 表保存为 excel 时出现错误？
TableRow tr = new TableRow();
TableCell yrs = new TableCell();
yrs.BorderWidth = 1;
yrs.BorderColor = System.Drawing.Color.Black;
yrs.Text = year.Substring(4);
tr.Cells.Add(yrs);
TableCell fname = new TableCell();
fname.BorderWidth = 1;
fname.BorderColor = System.Drawing.Color.Black;
fname.Text = test;
tr.Cells.Add(fname);
TableCell lname = new TableCell();
lname.BorderWidth = 1;
lname.BorderColor = System.Drawing.Color.Black;
lname.Text = test1.ToString();
tr.Cells.Add(lname);
TABULAR.Rows.Add(tr);
Response.Write(TABULAR);
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=test123.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter swWriter = new StringWriter();
HtmlTextWriter htwWriter = new HtmlTextWriter(swWriter);
TABULAR.RenderControl(htwWriter);
Response.Write(swWriter.ToString());
Response.End();

这里的问题是您正在处理 Table对象具体来说：
并且不以任何方式代表 Excel“表格”或其他任何内容。
通过修改响应标头来声明它是 Excel 文件只会欺骗浏览器，您没有有效的 Excel 文件
The problem here is you're dealing with a Table object which specifically:
and does not in any way represent an Excel 'table' or anything else.
Claiming it is an Excel file by modifying the response headers only tricks the browser, you do not have a valid Excel file
