业务需要，动态生成表，同一列中数据相同的单元格需要合并。
解决方案，创建Table控件处理类，代码如下：

 
/// <summary>表格控件相关操作类 
/// </summary> 
public static class aspTable 
{ 
/// <summary>合并行 
/// </summary> 
/// <remarks>版权信息：http://www.qqextra.com，http://t.qq.com/ls_man，http://blog.csdn.net/ls_man 2013-06-21 14:20:36</remarks> 
/// <param name="tbl">Table</param> 
/// <param name="startRow">起始行</param> 
/// <param name="endRow">结束行</param> 
/// <param name="colIndex">要合并的列索引</param> 
public static void SetRowSpan(Table tbl, int startRow, int endRow, int colIndex) 
{ 
int countRowSpan = 0; 
int spanRow = startRow; 
string spanText = tbl.Rows[startRow].Cells[colIndex].Text; 
for (int rowIndex = startRow; rowIndex <= endRow; rowIndex++) 
{ 
string currentText = tbl.Rows[rowIndex].Cells[colIndex].Text; 
//内容是否相同 
if (currentText == spanText) 
{ 
countRowSpan++; 
//移除被合并的单元格 
if (rowIndex != spanRow) 
{ 
tbl.Rows[rowIndex].Cells.RemoveAt(colIndex); 
} 
} 
else 
{ 
//合并 
tbl.Rows[spanRow].Cells[colIndex].RowSpan = countRowSpan; 
//从此行再向下比较（重置） 
countRowSpan = 0; 
spanRow = rowIndex--; 
spanText = currentText; 
} 
} 
//合并最后一项 
tbl.Rows[spanRow].Cells[colIndex].RowSpan = countRowSpan; 
} 
/// <summary>合并行，支持多列 
/// </summary> 
/// <remarks><SPAN style="FONT-FAMILY: Arial, Helvetica, sans-serif">版权信息：http://www.qqextra.com，http://t.qq.com/ls_man，http://blog.csdn.net/ls_man</SPAN><SPAN style="FONT-FAMILY: Arial, Helvetica, sans-serif"> 2013-06-21 15:24:34</remarks></SPAN> 
/// <param name="tbl">Table</param> 
/// <param name="startRow">起始行</param> 
/// <param name="endRow">结束行</param> 
/// <param name="colIndex">要合并的列索引</param> 
public static void SetRowSpans(Table tbl, int startRow, int endRow, params int[] colIndexs) 
{ 
ArrayList al = new ArrayList(colIndexs); 
al.Sort(); 
for (int i = al.Count - 1; i >= 0; i--) 
{ 
SetRowSpan(tbl, startRow, endRow, (int)al[i]); 
} 
} 
}
