对服务器端Table的操作
.NET自带的web控件table能实现对其编程控件各行、列的动态生成。以下就是一个简单的C#例子：
<html>
<head>
<script language="C#" runat="server">
void Page_Load(Object sender, EventArgs e) {
// 生成行和单元格
int numrows = int.Parse(DropDown1.SelectedItem.Value);
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();
c.Controls.Add(new LiteralControl("行 " + j.ToString() + "，单元格 " + i.ToString()));
r.Cells.Add(c);
}
Table1.Rows.Add(r);
}
}
</script>
</head>
<body>
<h3><font face="宋体">表的示例</font></h3>
<form runat=server>
<asp:Table id="Table1" Font-Name="宋体" Font-Size="9pt" CellPadding=5 CellSpacing=0 BorderColor="black" BorderWidth="1" Gridlines="Both" runat="server"/>
<p>
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>
<br>
表单元格:
<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>
<p>
<asp:button Text="生成表" runat=server/>
</form>
</body>
</html>
<html>
<head>
<script language="C#" runat="server">
void Page_Load(Object sender, EventArgs e) {
// 生成行和单元格
int numrows = int.Parse(DropDown1.SelectedItem.Value);
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();
c.Controls.Add(new LiteralControl("行 " + j.ToString() + "，单元格 " + i.ToString()));
r.Cells.Add(c);
}
Table1.Rows.Add(r);
}
}
</script>
</head>
<body>
<h3><font face="宋体">表的示例</font></h3>
