ASP.NET(C#) 畫表格

某噗友的作業，丟上來給他當參考

題目是：試寫一個網頁程式，當使用者輸入總列數(假設為X)與總列數(假設為Y)後，動態產生X*Y的表格



9x9.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="9x9.aspx.cs" Inherits="_9x9" %>

TableRow tRow = new TableRow();
Table1.Rows.Add(tRow);
for (int j = 0; j < Convert.ToInt32(TextBox2.Text); j++)
{
TableCell tCell = new TableCell();
tCell.Text = i.ToString() + j.ToString();
tRow.Cells.Add(tCell);
}

} } } }

static bool IsNumeric(object Expression)
{
bool isNum;
double retNum;
isNum = Double.TryParse(Convert.ToString(Expression), System.Globalization.NumberStyles.Any, System.Globalization.NumberFormatInfo.InvariantInfo, out retNum);
return isNum;
}
