實現(xiàn)代碼：<table class="table-detail"><tr> <th>名稱</th> <th>總計</th></tr></table><script type="text/javascript">var baseData = [ {"name":"昌大","total":"1000"}, {"name":"西江紅","total":"2000"}];window.onload = function() { var mytable = document.getElementsByTagName('table')[0]; for(var i = 0; i < baseData.length; i++) { var tr = mytable.insertRow(mytable.rows.length); var obj = baseData[i]; for(var p in obj) { var td = tr.insertCell(tr.cells.length); td.innerText = obj[p]; } }}</script>但是，我想要增加一列，自動生成序號，如下圖。
