动态RDLC报表类DynamicReport：数据表节点数据填充
数据表部分是最麻烦的，可以添加多个数据表，可以设置多维表头，可以设置多字段的统计行，不同的列可以采用不同的样式。在传入数据表前需要先传入列样式、多维表头，数据表和统计列是同一时间传入的，页眉和页脚则需要在数据表后传入。
在这里最多可以设置三行表头，从上到下依次是hearderTop、hearderMerge和数据表中的列。表头的样式包含如下几部分：
public string ColoumName { get; set; } //列名
public float ColoumWidth { get; set; } //列宽
public TextAlign TextAlign { get; set; } //对齐
public ConsoleColor ConsoleColor { get; set; } //颜色
public Boolean IsShortDate { get; set; } //显示短日期格式
多维表头的数据表结构是：
DataTable hearderMerge = new DataTable();
hearderMerge.Columns.Add("CellNumber", Type.GetType("System.Int32"));
hearderMerge.Columns.Add("CellValue", Type.GetType("System.String"));
CellNumber代表占用多少列宽度，1为一列，2为合并二列，总列数不能超过或少过数据表的列数；CellValue就是显示的名称。
统计行可以是单列或多列，以string方式传入，不同列用逗号分隔，如“列名1,列名3”，可以是任意列，可以相邻或间隔，但必须是数据表中存在的列并且值可以相加。当只有一列统计时在此列的前面显示“统计：”，如果是第一列则不显示。
数据表会生成DataSets节点和Tablix节点。
