ExpressSpreadSheet控件作为一个真正的交叉平台组件库，可支持Delphi4、5、6、7，C＋＋Builder 4、5、6和Kylix 2。该控件可为用户提供一个比较好的方法，以便在自己的设计中介绍电子数据表的功能。但是不要被这些产品的名字所迷惑……由于该控件有着极其灵活的表示结构，它可以为用户提供高度的用户界面控制，因此用户同样可以用该控件来创建一个高级的数据表目录。来引导用户使用ExpressSpreadSheet控件，下面简要的列出了该控件可用的功能：

• 内建WorkSheet支持——ExpressSpreadSheet控件为用户提供了通过采用/不采用多表单创建工作笔记的功能——当顾客需要制定时，ExpressSpreadSheet不会限制用户的创造性。
  

• 有多种显示式样——通过一个简单的属性设置，用户就可以将MS Excel 97或者XP的式样加到自己的应用程序中。
  

• 支持自定义图画——就像其他的Developer Express技术一样，用户可以通过其自带的Painter类来完全控制ExpressSpreadSheet控件的外观。
  

• 绝对的和相对的公式选址。

• 载入和保存数据——ExpressSpreadSheet控件允许用户从XLS文件中载入数据和保存数据至XLS文件中——此时，可以保持当前的显示外观（单元数据格式、单元格样式等等）。此外，ExpressSpreadSheet控件还可保存工作笔记内容到流文件（流出），然后再从一个流文件载入这些数据到其他的工作笔记中（流回）。

• 内建的操作符和函数——ExpressSpreadSheet控件通过一些标准的函数来传输内容，因此简化了公式结构，使得工具箱看起来简洁明了。

• 自定义函数注册——灵活性和控制是ExpressSpreadSheet控件的核心。通过Shipping控件，我们增加了很多的功能，但是用户仍可根据需要添加自己的函数，这是非常容易的！

• 完整的单元格样式控制——支持独特的单元格格式。自定义的单元格边界样式，背景和前景色，笔刷和字体属性，垂直和水平对齐的文本格式。

• 单元格边界和边缘样式

• 填充图案

• 背景色

• 文本格式
  

• 直观的单元格管理——用户可在执行类似Excel操作之后进行填充，管理单元格和它们的内容就像1－2－3一样的简单。

• 合并/拆分单元格——在ExpressSpreadSheet控件中合并和填充单元格并不简单，但是它绝对可靠。这就意味着合并单元格中的内容绝对不会丢失。当合并的单元格进行拆分时，所有的单元格（除了最主要的）将包含它们在合并前的原始的单元格内容。
  

• 数据分类——如同Excel一样，ExpressSpreadSheet控件支持对一个或者多个列排序。

• 支持行和列的自动大小调整

• 锁定/解锁行和列
  

• 撤消/重做——ExpressSpreadSheet控件将保存所有的格式和编辑操作，因此用户可通过Ctrl＋Z和Ctrl＋Y快捷键来分别执行撤消/重做。

• 可自定义外观——因为该控件灵活的设计，用户可以控制ExpressSpreadSheet控件的显示特征，以此来为终端用户创建直接的数据登录窗体。

• 优秀的设计和结构——ExpressSpreadSheet控件具有灵活性。举例来说，工作表单的尺寸、打开笔记的数量、单元格内容的长度、相关的表单、行和列的数目都只被可用的内存和系统资源所限制。

• 通过ExpressPrinting系统支持完整的绘画功能——假如用户拥有ExpressPrinting系统，用户可以简便的绘制ExpressSpreadSheet的内容——用户甚至可以设置一个绘制的面积，就像在Excel中所做的那样。
