完成用户注册、登录页面，实现数据的真实操作。

编写小九九：

protected void Page_Load(object sender, EventArgs e)

{

HtmlTable table = new HtmlTable();

for (int i = 1; i <= 9; i++)

{

HtmlTableRow row = new HtmlTableRow();

for (int j = 1; j <=i; j++)

{

HtmlTableCell cell = new HtmlTableCell();

cell.InnerText = j + "*" + i + "=" + j * i;

row.Cells.Add(cell);

}

table.Rows.Add(row);

}

table.Width = "100%";

table.CellSpacing = 0;

table.CellPadding = 10;

table.Border = 1;

table.BorderColor = "#000000";

this.p1.Controls.Add(table);

}
