十万火急！请高手看一下。(100分)

十万火急！
各位高手，本人现在急需了解在DELPHI中，怎么对
EXCEL 的数据表进行操作，有相关控件的最好.我知道
在DELPHI 5 中，用OLE 和SERVER 中的控件，但详细用
法不是很了解，望各位高手能指点一下。
（来信：qie_zi@263.net 附例子源代码最好了）
谢谢！

在这里用EXCEL来查，很多的。

Delphi 带有 Word 自动化的例子，Excel 的没有，用法都很简单，关键是要了解 Excel
支持的接口，可以看一看 Excel2000.Pas 的代码。

{TArmExcel 用EXCEL做报表,
1。设置纸张、页眉页脚、网格线
2。导出数据集的数据—（对部分字段）求和
3。可以选择工作表，打印预览
4。像STRINGGrid一样使用CellS属性
5。有ONExportProgress事件与用户交互
