how to add any rows to table in runtime with asp.net?

<asp:table id="Table1" runat="server" borderstyle="Solid" borderwidth="1" width="100px" xmlns:asp="#unknown"></asp:table>

//Create a Label control to show a message
Label lbl = new Label();
lbl.Text="Hello world";

//Create a TableRow control
TableRow tr = new TableRow();

//Create a TableCell control
TableCell tc = new TableCell();

//Add the lable to TableCell control
tc.Controls.Add(lbl);

//Add TableCell control to TableRow control
tr.Cells.Add(tc);

//Finally add the TableRow to Table control
Table1.Rows.Add(tr);
