动态AdvStringGrid完美示例 (AdvStringGrid使用技巧/Cells)

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

    (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。
