kam*_*ilf 2 css html-table border

我正在为我的网站设计样式表。我想要一张桌子,其中第一个 TR 没有边框,而其他 TR 和他们的 TD 有边框。代码:http : //jsfiddle.net/azq6xfnr/或这里:

.table2 {
  border: 1px solid black;
  border-collapse: collapse;
  text-align: center;
}

.table2 .header {
  background-color: #d8ff93;
  color: #126f06;
  border: 0;
}

.table2 td {
  border: 1px solid #53f673;
  padding: 10px;
}

.table2 tr:not(.header):nth-child(odd) {
  background-color: #3cde53;
}
