本例说明一种报表组件的实现方法。
原理：将各个表格元素，以图像的方式设置、添加到纸张画布上，生成图像，打印图像。
功能：
1、支持SQL Serrver、Access数据库，如需其他数据库，也可很方便的添加到代码中，自动获取数据表，在元素中可选择添加字段到报表中；
2、报表元素可自由拖放、设置大小、内容、字体、字体样式等（元素非PictureBox组件）；
3、支持全程的“撤销”、“重做”；
4、可保存、读取报表文件；
5、预览、打印没加上去，原理就是根据元素生成一幅或多幅图像，再输出到打印机，自行修改添加。
这里说明一下，这只是个规划草稿，只是描述了一种报表组件的设计方式，所以代码写的较为繁琐、冗余，代码无委托线程等，所以比较容易看明白。
