表行：
<asp:DropDownList ID="DropDown1" runat="server">
<asp:ListItem Value="1">1</asp:ListItem>
<asp:ListItem Value="2">2</asp:ListItem>
<asp:ListItem Value="3">3</asp:ListItem>
<asp:ListItem Value="4">4</asp:ListItem>
</asp:DropDownList>
表列
<asp:DropDownList ID="DropDown2" runat="server">
<asp:ListItem Value="1">1</asp:ListItem>
<asp:ListItem Value="2">2</asp:ListItem>
<asp:ListItem Value="3">3</asp:ListItem>
<asp:ListItem Value="4">4</asp:ListItem>
</asp:DropDownList>

<asp:Button Text="创建表" runat="server" ID="Button1" />
</div>
</form>

我的问题都在上面，大大们给的建议
- DropDown1.SelectedItem.Value为string型，要转化为int
- void Page_Load(Object sender, EventArgs e) {
- int numrows = int.Parse(DropDown1.SelectedItem.Value);///将DropDown1值转换为int型
- int numcells = int.Parse(DropDown2.SelectedItem.Value);
- for (int j = 0; j < numrows; j++) {
- TableRow r = new TableRow();
- for (int i = 0; i < numcells; i++)
- {
- TableCell c = new TableCell();
- //TableCell 为单元格 c.Controls.Add 意思是在单元格中添加控件，new LiteralControl 创建了LiteralControl 控件
- //显示第几行第几列
- c.Controls.Add(new LiteralControl("行" + j.ToString() + ", 列" + i.ToString
- r.Cells.Add(c); //将Tablecell添加到table的row中
- }
- Table1.Rows.Add(r);// 将行添加到table中
- }
- }
- 就是动态来添加table的操作
