รบกวนดูโค๊ด การ Generate table ให้หน่อยครับ ว่าคสรปรับยังไงดี?

public void Tabletag(frmInsertTable frm)
        {
            //string src = frm.SourceImage;
            int width = 100;
            string p = "%";
            int i = 0;
            int j = 0;

            string tbTag = "<table @border @width><@tr><@td><@/td><@/tr></table>";

            tbTag = tbTag.Replace("@border", "border=\"" + frm.Border + "\"");
            tbTag = tbTag.Replace("@width", "width=\"" + width + p + " \"");

            for (j = 0; j <= int.Parse(frm.Rows.ToString())-1; j++ )
            {
                tbTag = tbTag.Replace("@tr", "tr");

                for (i = 0; i <= int.Parse(frm.Column.ToString()) - 1; i++)
                {
                    tbTag = tbTag.Replace("@td", "td");
                    tbTag = tbTag.Replace("@/td", "/td");

                }
                tbTag = tbTag.Replace("@/tr", "/tr");

            }
            
            object sel = ((IHTMLSelectionObject)document.selection).createRange();
            try
            {
                ((IHTMLTxtRange)sel).pasteHTML(tbTag);
            }
            catch { }
        }
