Hi ,
Try this

int countTimes = 0;
 protected void Button2_Click(object sender, EventArgs e)
 {
     if (ViewState["countTimes"] == null)
     {
         countTimes = 1;
     }
     else
     {
         countTimes = Convert.ToInt32(ViewState["countTimes"]);
     }
     for (int i = 0; i < countTimes; i++)
     {
         TableRow row = new TableRow();
         TableCell cell = new TableCell();
         TextBox txt = new TextBox();
         txt.ID = "txt"+i;
         TextBox txt1 = new TextBox();
         txt1.ID = "txt" + i;
         TextBox txt2 = new TextBox();
         txt2.ID = "txt" + i;
         TextBox txt3= new TextBox();
         txt3.ID = "txt" + i;
         TextBox txt4 = new TextBox();
         txt4.ID = "txt" + i;
         TextBox txt5 = new TextBox();
         txt5.ID = "txt" + i;

         TextBox txt6 = new TextBox();
         txt6.ID = "txt" + i;
         cell.Controls.Add(txt);
         cell.Controls.Add(txt1);
         cell.Controls.Add(txt2);
         cell.Controls.Add(txt3);
         cell.Controls.Add(txt4);
         cell.Controls.Add(txt5);
         cell.Controls.Add(txt6);

         row.Controls.Add(cell);
         Table1.Controls.Add(row);
     }
     countTimes = countTimes + 1;
     ViewState.Add("countTimes", countTimes);
 }

<div>
    <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
    <br />
    <asp:Table ID="Table1" runat="server">
    </asp:Table>
</div>

for (int i = 1; i <= Convert.ToInt32(TextBox1.Text ); i++)

{

TableRow tr = new TableRow();

for (int j = 1; j <= 3; j++)

{

TableCell td = new TableCell();

TextBox c_text = new TextBox();

c_text.Visible = true; 

c_text.Text = "R"+i.ToString()+j.ToString();

c_text.ID = "R" + i.ToString() + j.ToString();

td.Controls.Add(c_text);

tr.Cells.Add(td);
