这是按钮点击的功能：
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 即可。标题栏不会调整自身以适应我提供的值（零售客户组等）。请建议 此类中需要进行修改以启用自动调整。
谢谢。
答案 0 :(得分：1)
在您的CreateContent方法中，您有以下硬编码值：
c.CellValue = new CellValue("12334");
使用您要显示的文本框的值更改它。
要设置标题的宽度，您需要添加列和单元格，因为您需要列来定义宽度，以下文章将为您提供一些帮助：

答案 1 :(得分：0)
我花了很多时间在Google上搜索与OpenXml相关的问题。 我终于通过将OpenXml功能与Excel VBA相结合，找到了解决我的问题的方法。 所以， 我有Excel - 宏启用文件（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，它就像：
一样简单Sub Workbook_Open（） ActiveSheet.Columns.AutoFit 结束子
希望它可能会有所帮助。
