摘要
Excel是一个在各个领域中被广泛应用的电子表格软件。通过它，我们可以很好的组织管理数据，对数据进行统计分析等。在实际应用中，我们发现经常需要根据某种特定的条件，特殊显示部分数据。虽然这种功能可以通过Excel宏来实现，但每次编写类似的代码使人感觉跟不方便。Excel同其它Office组件一样，提供了通过插件进行功能扩展的可能。通过编写和安装插件，我们可以几乎任意地扩展Excel的功能，为我们的工作提供极大的便利。本文详细介绍了一个Excel条件格式化软件的设计和实现。该软件使用COM组件技术，根据Office插件的接口要求，设计了一个Excel的插件。该插件在Excel应用程序的窗口中增加一个工具栏，并在其上创建了一个按键，用于打开格式化设置窗口。软件可以对用户输入的、用字符串表达的判断条件进行计算，并根据计算结果，将满足条件的单元数据设置为用户选择的特殊格式（字体、颜色、字号、修饰等）

Abstract
Excel is an electronic sheet software which is extensively used in various fields. By using it, we can organize and manage data, statistically analysis data easily. In practical applications, we need it usually need to specially show some data under certain conditions. This function can be achieved by using Excel macros. However，such a method is inconvenient in writing similar codes in each time. Excel, as long as other Microsoft Office softwares, povides a standard plug-in interface, also called add-in, to allow users to expand its functionalities. By writing addins for Excel, we can almost unlimitedly to expand its functionality and makes our work more easily and effectively. This paper introduces the design and implementation of an Excel conditional formatting addin, which is implemented by the COM component technique according to the interface requirements of Excel. The conditional formatting addin adds a new Toolbar into Excel, on which there is a button to be used to open the format setting dialog. The software can calculate the results of the condition expressions inputted by the user in the form of string, and according to the result, it sets the format of the cells matching the use-defined condition to special formats (font, color, font size and decoration) that was inputted by the user.
