流程平台：子表控件（二） - 属性、事件、方法

子表控件的元数据如下：属性、事件、方法：

    public class SheetSubTableSZ : WebControl, ISheetControl{//     分隔符public const char Separator = ';';public const string SeqNoColumnName = "序号";//     添加按钮public Button Add;//     子表的编辑视图public Table EditTable;//     子表的显示视图public GridView ItemView;public Button Remove;public Label Result;public Button Update;public SheetSubTableSZ();public override Color BackColor { get; set; }//     当前表的列定义protected Dictionary<string, DataColumn> Columns { get; }//     绑定字段public string DataField { get; set; }//     如果使能，则显示编辑控件和选中列public override bool Enabled { get; set; }public override string ID { get;
