这是按钮单击的功能：

protected void Button1_Click(object sender, EventArgs e)
        {
            string qwe = TextBox1.Text;
            string ert = TextBox2.Text;
            string filename = @"D:\\ExcelOpenXmlWithImageAndStyles.xlsx";
            CreateExcelOpen exp = new CreateExcelOpen();
            exp.BuildWorkbook1(filename);
        }

这是我的要求：

1 .我需要将两个文本框的值传递给两个单元格（现在包含值 12334 和 124515）。

2 . 标题列不会自行调整以适应我提供的值（零售客户组等）。请建议此类中所需的修改以启用自动调整。

谢谢你。

在您的CreateContent方法中，您具有硬编码值，例如：

c.CellValue = new CellValue("12334");

使用要显示的文本框的值更改它。

要设置标题的宽度，您必须在单元格中添加列，因为您需要列来定义宽度，以下文章将对您有所帮助：

我花了很多时间在谷歌上搜索 OpenXml 相关问题。通过将 OpenXml 功能与 Excel VBA 相结合，我终于找到了解决问题的方法。所以，我有 Excel - 启用宏的文件 (xlsm) 作为我的项目的模板。无论在 OpenXml 中难以实现什么逻辑，我都转向了 VBA。例如，对于 AutoFit，它很简单：

Sub Workbook_Open() ActiveSheet.Columns.AutoFit End Sub

希望它可能会有所帮助。
