原理就是先声明常量，包括列数，行数，各列的属性，然后在程序的其它过程用这些常量来控制Cells。非常方便，便于修改和移植!
以下为窗体整体代码，中间有说明。此段代码不光有动态AdvStringGrid的完美示例，还有一般窗体的常用的过程，比较窗体初始化，刷新过程。
此窗体，只需要简单准备如下，即可运行：
1，添加一个TAdvStringGrid，并命名为strGrid1。
2，设置：TAdvStringGrid-->option-->goEditing=true
TAdvStringGrid-->enableGraphics=true
3，修改Form名称为form1，或替换以下代码中的form1为当前窗体的名字。
4，将以下代码覆盖原来的代码。
5，关联以下过程(只需要在窗体和strGrid1控件属性-事件页中双击相关项即可完成关联。)
FormCreate
FormShow
strGrid1CanEditCell
strGrid1GetAlignment
strGrid1GetCellColor
strGrid1GetEditorType

//声明常量数组，保存Cells的各种属性，各种属性含义如下：
{0-显示
1-编辑
2-必输
3-类型
4-对齐
5-颜色

8-是否从数据库中读取
9-数据表名称
10-字段名
11-字段长度
12-文本中读取
13-文本中位置 }

(以上过程在Delphi6中测试通过。)

这样，如果修改Cells相关的属性，只需要修改数组cColProp1相关的值就可以实现了，很方便的。
关于修改cColProp1，你可以直接在上面的代码窗口中修改，但如果列相当多的话，这样改起来也是相当麻烦的，而且容易改错，也是不方便的!
对此，我做了一个excel模板：动态Cells设定工具表，如附件。

通过这个模板，可以自动生成静态数组cColProp1和静态列号，修改起来也很直观，很方便。
修改后，将生成的静态数组cColProp1和静态列号复制到代码里即可。
