C# 报表设计器（winform 设计端）开发与实现生成网页的HTML报表开放源码及调试

记得2010年之前，公司的项目基本上都要用到报表，以前我们常用的方法就是针对客户的需求来定制化开发（基本上是死写代码）来实现，经常导致项目经常性的延期，因为客户的需求经常会变化，随着用户的使用认知度的提高，对报表的要求越来越高，导致程序员不停的修改代码来实现，效率不高、结束遥遥无期。。。非常的痛苦；当然市面上有很多报表开发工具可以实现，但是针对小公司来说采购一套这样的系统的成本也非常的高，所以我们决定自己来开发一套像目前的润乾、FineReport 这样的报表设计器，来实现快速的报表设计制作。

当初为了开发这样的系统，花费的了很长的时间学习查阅各种资料，其痛苦只有程序员才能体会，因为没有任何现成的实例代码可供参考，只有看别人的思路来一步步的摸索，本文将我们当初设计制作的报表设计器的功能分享出来，让有需要的或想开发报表设计的朋友们提供一个参考，尽量少走很动弯路，设计端可以直接使用，但是计算引擎和网页的计算的源码就不能分享出来了（请不要介意，因为涉及到公司的保密原因）

记得当初为了制作报表设计器，在网上查找有没有相关的实例资料，找了很久，也是没有找到合适的，后来发现 SourceGrid 可以实现单元格的合并拆分功能，所以决定修改实现winform端的报表设计。下面我将制作的E_Report 报表控件抽取出来建立一个简易的Winform的可运行的实例提供给大伙下载，希望能给你的开发提供一点帮助和借鉴；当然你可以直接使用也可以，里面的设计功能基本全部能。

抽取出来的源码包含：E_Report 报表设计自定义控件DLL源码; EReportDemo 建立的简易Winform 端设计器使用DLL的实例源码；

一、运行效果

实例中，只做了一个简单的效果，工具栏的按钮在单元格右击属性中都有，只是放了几个常用的在工具导航栏中（右击单元格属性可以看到设计导航）

可以进行单元格的合并、拆分、字体、颜色、背景、边框等的设置，朋友们可以自己编写保存发布等功能，实现报表的真实功能；

例如单元格属性（其他还有很多的属性，自己下载源码后运行起来就能看到了）

对表格的斜线、斜线文字有很好的支持；可以设置表头、表位、标题等实际效果图如下

二、使用介绍

1、页面初始化的时候，通过 ReportDoc 类初始报表的行列及单元格属性
