Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.ParagraphFormat.Alignment = ParagraphAlignment.Center;

//Start table
builder.StartTable();

builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.First;
builder.Write("One");

builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.First;
builder.Write("Two");

builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.None;
builder.CellFormat.HorizontalMerge = CellMerge.First;
builder.Write("Header");

builder.InsertCell();
builder.CellFormat.HorizontalMerge = CellMerge.Previous;
builder.Write("Header");

builder.InsertCell();
builder.CellFormat.HorizontalMerge = CellMerge.None;
builder.CellFormat.VerticalMerge = CellMerge.First;
builder.Write("Column");

builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.First;
builder.Write("Column");
builder.EndRow();

//Insert second Row
builder.InsertCell();
builder.CellFormat.VerticalMerge = CellMerge.Previous;
builder.Write("One");

builder.InsertCell();

尝试将Inherits的值设置为类的名称：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="usageDisp.aspx.cs" Inherits="WebApplication1.usageDisp" %>

来自MSDN：

继承 - 为要继承的页面定义代码隐藏类。这个可以是从Page类派生的任何类。此属性用于 CodeFile属性，包含源文件的路径代码隐藏类。 Inherits属性在区分大小写时使用C＃作为页面语言，使用Visual时不区分大小写基本作为页面语言。
