public string GetDataTableAsHTML(DataTable thisTable)
        {
            System.Text.StringBuilder sb = new System.Text.StringBuilder();
            sb.AppendFormat(@"<caption> Total Rows =");
            sb.AppendFormat(thisTable.Rows.Count.ToString());
            sb.AppendFormat(@"  </caption>");
            sb.Append("<TABLE BORDER=1>");
            sb.Append("<TR ALIGN='CENTER' style='background-color: #3d68d0;color:White;font-size:smaller;font-family:Tahoma '>");
            //first append the column names.
            foreach (DataColumn column in thisTable.Columns)
            {
                sb.Append("<TD><B>");
                sb.Append(column.ColumnName);
                sb.Append("</B></TD>");
            }

            sb.Append("</TR>");

            // next, the column values.
            foreach (DataRow row in thisTable.Rows)
            {
                sb.Append("<TR ALIGN='CENTER' style='font-size:smaller;font-family:Tahoma'>");

                foreach (DataColumn column in thisTable.Columns)
                {
                    sb.Append("<TD>");
                    if (row[column].ToString().Trim().Length > 0)
                        sb.Append(row[column]);
                    else
                        sb.Append("&nbsp;");
                    sb.Append("</TD>");
                }

                sb.Append("</TR>");
            }
            sb.Append("</TABLE>");

            return sb.ToString();
        }
