Asp.net_Table控件の单元格纵向合并示例

时间:2022-05-20 17:08:05

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: 

复制代码代码如下:

/// <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]); 



需要注意的几点,起始行一般设置为1,因为0是标题行;结束行一般设置为Table的总行数-1即可(最后一行)。
