PCB决策引擎:多维决策表转决策树

准备设计一个PCB使用的决策引擎，需要用到决策表，而单维决策表不能满足业务要求，

这里主要是为了实现：用户编辑的是决策表，实际底层存储的是树结构,树的的各个节点挂上业务决策逻辑.

这里将多维决策表转决策树构思整理如下:

 一.决策表（多维表头结构UI编辑界面）

        用户可编辑的规则界面，规则决策表交由用户配制，可实现任意多表头结构的决策表。

二.决策树（TreeNode 简易界面）

    TreeNode 是从决策表中转换过来的，可以实现节点决策控制，后续转换TreeNodeVIew用户可以附加属性编辑

                   左表头                                                                    上表头

三.DB数据库存储结构

               多表头结构：

              

             交叉行列号存储值表：

             

四.决策表转决策树 C#程序实现代码：

    /// <summary>
        /// 采用TreeNode做为树根结点做为起始点递归实现
        /// </summary>
        /// <param name="TreeNode_"></param>
        private void ExcelHeadToTreeNodes(TreeNode TreeNode_)
        {
            T_RuleTableRowColumnMultiExpression ModTableCell_ = (T_RuleTableRowColumnMultiExpression)TreeNode_.Tag;
            if (ModTableCell_ == null)
                return;

            int StartColumnIndex = 0;
            int EndColumnIndex = 0;
            int ColumnCount = 0;
            int StartRowIndex = 0;
            if (ModTableCell_.DimensionNum == 1) //维度1  列
            {
                ColumnCount = ModTableCell_.EndColumnIndex - ModTableCell_.StartColumnIndex + 1;
                if (ColumnCount == 1) return;
                StartColumnIndex = ModTableCell_.StartColumnIndex;
                EndColumnIndex = ModTableCell_.EndColumnIndex;
                StartRowIndex = ModTableCell_.StartRowIndex + 1;
            }
            else if (ModTableCell_.DimensionNum == 2)//维度1  行
            {
                ColumnCount = ModTableCell_.EndRowIndex - ModTableCell_.StartRowIndex + 1;
                if (ColumnCount == 1) return;
                StartColumnIndex = ModTableCell_.StartRowIndex;
                EndColumnIndex = ModTableCell_.EndRowIndex;
                StartRowIndex = ModTableCell_.StartColumnIndex + 1;
            }
            else
            {
                return;
            }
            int LayerIndexCurrent = ModTableCell_.LayerIndex + 1;
            int i = 1; //层次
