This is my version of it, with added the possibility to "highlight" some rows based on a generic rule (rowHighlightRule parameter).

  public static string ToHTML(this DataTable dt, Func rowHiglithRule)
    {

        if (dt == null) throw new ArgumentNullException("dt");

        string tab = "\t";

        StringBuilder sb = new StringBuilder();
        sb.AppendLine(tab + tab + "");

        // headers.
        sb.Append(tab + tab + tab + "");

        foreach (DataColumn dc in dt.Columns)
        {
            sb.AppendFormat("", dc.ColumnName);
        }

        sb.AppendLine("");

        // data rows
        foreach (DataRow dr in dt.Rows)
        {
            if (rowHiglithRule != null)
            {

                if (rowHiglithRule(dr))
                {
                    sb.Append(tab + tab + tab + "");
                }
                else
                {
                    sb.Append(tab + tab + tab + "");
                }
            }
            else
            {
                //Non ho alcuna regola, quindi caso normale.
                sb.Append(tab + tab + tab + "");
            }

            foreach (DataColumn dc in dt.Columns)
            {
                string cellValue = dr[dc] != null ? dr[dc].ToString() : "";
                sb.AppendFormat("", cellValue);
            }

            sb.AppendLine("");
        }

        sb.AppendLine(tab + tab + "
{0}
{0}
");


        return sb.ToString();
    }
