HTML Close Table Borders

Good day could you please tell me how do I close the borders for this table, (bottom and right border) 



HTML

output = output + "<table class='tableSize' align='center' frame='border'><tr><td style='width:20%;vertical-align: top;'>";
output = output + "<table border='1' align='center' cellspacing='0' style='border-color:#EEE;width:95%;margin:0px 0px 0px 0px' id='billingAdd'>";
output = output + "<td class='rowHead'>Consecutivo</td><td class='rowVal'>" + AvanceDiario.Auto_IDStr + "</td></tr>";
output = output + "<td class='rowHead'>Fecha</td><td class='rowVal'>" + AvanceDiario.spdate + "</td></tr>";
output = output + "</table>";

CSS

  .tableSize{
          width: 80%;
          margin: 0px auto;
          margin-top: 10px;
  }
