@MichaelRandall 不添加我想创建运行时点击事件
@T.S.不显示数据，但我想创建运行时单击事件菜单旅行
使用Runtime T4 Template 会更干净。

【解决方案1】：

1个文件只使用一次Html标签，多次使用Table标签

我的代码：-

private void Form2_Load(object sender, EventArgs e)
    {
        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        System.Text.StringBuilder sb1 = new System.Text.StringBuilder();

        Microsoft.Office.Interop.Excel.Application ExcelApp = new Microsoft.Office.Interop.Excel.Application();
        Workbook xlWorkBook = ExcelApp.Workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet);
        sb.Append("<html>");
        sb.Append("<head></head>");
        sb.Append("<body>");
        sb.Append("<table border=1>");
        sb.Append("<tr style=height:30px;>");
        sb.Append("<td style='min-width:50px;text-align:center;font-size:20px;background-color:#c0c0c0;' colspan=6>");
        sb.Append("<nobr><b>Meru Malakiya</b></nobr>");
        sb.Append("</td>");
        sb.Append("</tr>");
        sb.Append("<tr style='height:30px;'>");
        sb.Append("<td style='min-width:50px;text-align:center'>");
        sb.Append("<nobr><b>No.</b></nobr>");
        sb.Append("</td>");
        sb.Append("<td style=min-width:50px;text-align:center>");
