asp.net 创建表格中的合并列问题

请问如何使用DataTable创建复杂的表格？
比如下面是代码(并附有例图):

<table width="400" border="1">
<tr>
<th>名称</th>
<th>日期</th>
<th colspan="3">编辑</th>
</tr>
<tr>
<td rowspan="2">张三</td>
<td rowspan="2">01-16</td>
<td>修改</td>
<td rowspan="2">删除</td>
<td rowspan="2">编辑</td>
</tr>
<tr>
<td>问候</td>
</tr>
<tr>
<td rowspan="2">李四</td>
<td rowspan="2">12-25</td>
<td>修改</td>
<td rowspan="2">删除</td>
<td rowspan="2">编辑</td>
</tr>
<tr>
<td>问候</td>
</tr>
</table>

---------------
请高手不吝赐教！
不好意思，后来又多加了一行问候，如果可以，希望能实现！

你的意思是不是要用Table控件动态创建？试试看下面的代码
Table tab = new Table();
tab.Width = 400;
tab.BorderWidth = 1;

TableHeaderRow th = new TableHeaderRow();
th.Cells.Add(new TableCell());
th.Cells.Add(new TableCell());
th.Cells.Add(new TableCell());
th.Cells[0].Text = "名称";
th.Cells[1].Text = "日期";
th.Cells[2].Text = "编辑";
th.Cells[2].ColumnSpan = 3;
tab.Rows.Add(th);

TableRow tr1 = new TableRow();
tr1.Cells.Add(new TableCell());
tr1.Cells.Add(new TableCell());
tr1.Cells.Add(new TableCell());
tr1.Cells.Add(new TableCell());
tr1.Cells.Add(new TableCell());
tr1.Cells[0].Text = "张三";
tr1.Cells[1].Text = "01-16";
tr1.Cells[2].Text = "修改";
tr1.Cells[3].Text = "删除";
tr1.Cells[4].Text = "编辑";
tr1.Cells[0].RowSpan = 2;
tr1.Cells[1].RowSpan = 2;
tr1.Cells[3].RowSpan = 2;
tr1.Cells[4].RowSpan = 2;
tab.Rows.Add(tr1);

TableRow tr2 = new TableRow();
tr2.Cells.Add(new TableCell());
tr2.Cells[0].Text = "问候";
tab.Rows.Add(tr2);

TableRow tr3 = new TableRow();
tr3.Cells.Add(new TableCell());
tr3.Cells.Add(new TableCell());
tr3.Cells.Add(new TableCell());
tr3.Cells.Add(new TableCell());
tr3.Cells.Add(new TableCell());
tr3.Cells[0].Text = "李四";
tr3.Cells[1].Text = "12-25";
tr3.Cells[2].Text = "修改";
tr3.Cells[3].Text = "删除";
tr3.Cells[4].Text = "编辑";
tr3.Cells[0].RowSpan = 2;
tr3.Cells[1].RowSpan = 2;
tr3.Cells[3].RowSpan = 2;
tr3.Cells[4].RowSpan = 2;
tab.Rows.Add(tr3);

TableRow tr4 = new TableRow();
tr4.Cells.Add(new TableCell());
tr4.Cells[0].Text = "问候";
tab.Rows.Add(tr4);

Page.Controls.Add(tab);

你说的是System.Data.DataTable还是System.Web.UI.WebControls.Table或者是System.Web.UI.HtmlControls.HtmlTable?
如果只是想用C#代码生成一个html表格的话那就是System.Web.UI.WebControls.Table和System.Web.UI.HtmlControls.HtmlTable
都可以
System.Web.UI.WebControls.TableCell里的"ColumnSpan"和"RowSpan"属性用来合并单元格的，名称和用法都和html里的table一样
---------------------------------------------------
System.Data.DataTable是不能以这种格式保存数据的

<table border="1">
<tr>
<th>名称</th>
<th>日期</th>
<th colspan="3">编辑</th>
</tr>
<tr>
<td rowspan="2">张三</td>
<td rowspan="2">01-16</td>
<td>修改</td>
<td rowspan="2">删除</td>
<td rowspan="2">编辑</td>
</tr>
<tr>
<td>问候</td>
</tr>

<tr>
<td rowspan="2">李四</td>
<td rowspan="2">12-25</td>
<td>修改</td>
<td rowspan="2">删除</td>
<td rowspan="2">编辑</td>
</tr>
<tr>
<td>问候</td>
</tr>
</table>

用Dreamweaver新建个html，ctrl+alt+t
生成个表格出来，用设计界面，鼠标选中要合并的行或列，下边有属性菜单，合并单表格或拆分单元格。学懂了，自己想怎样就怎样
