HtmlForm form2 = new HtmlForm();
Panel[,] panelAd = new Panel[mm, 3];
Table mytable = new Table();
....
mytable.Controls.Add(trow_7);
if (col < 3)
{
panelAd[row, col].Controls.Add(mytable);
this.form2.Controls.Add(panelAd[row, col]);
col++;
}

col = 0;
panelAd[row, col].Controls.Add(mytable);
this.form2.Controls.Add(panelAd[row, col]);
}
