我一直在尝试使用经典 ASP 将图像置于 Excel 导出文件的中心。我尝试了一切并求助于 CSS。 CSS 无效(示例如下):
img {
position: absolute;
top: 0; bottom:0; left: 0; right:0;
margin: auto;
}
和
img.center {
display: block;
margin: 0 auto;
}
我尝试将图像放在 div 中并使 div 居中。那也没有用。我在 img 标签中有这样的图像:
<img border=0 id= "img" name= "img" src="pic.jpg" height ="100" width= "1000">
当我将文件导出到 Excel 并打开它时，图片总是在最左边。
最佳答案
虽然简单的 Excel 文件可以通过 ASP Classic 简单地通过设置页面的标题来创建，但您通常需要更多的控制。

听起来您需要使用 OpenXML 而不是 HTML。
以下是如何使用 OpenXML 将图像插入特定单元格的示例:https://social.msdn.microsoft.com/Forums/office/en-US/157e2fab-ed30-43a5-9824-e144d673a5b7/insert-images-into-specific-excel-cells-using-openxml?forum=oxmlsdk
