<html>
<head>
    <title>table添加/删除行</title>
</head>
<body>
<table id="testTbl" border=1>
    <tr>
        <td>性别</td>
        <td>姓名</td>
        <td>年龄</td>
    </tr>
    <tr>
        <td>
            <select name="a">
              <option value="男">男</option>
              <option value="女">女</option>
            </select>
        </td>
        <td>
            <input type="text" name="b">
        </td>
        <td>
            <input type="text" name="c">
        </td>
    </tr>
</table>
<input type="button" name="Submit2" value="添加" onclick="addRow()">
<script>
function addRow(){
    //添加行
    var newTr = testTbl.insertRow();
    //添加列
    var newTd0 = newTr.insertCell();
    var newTd1 = newTr.insertCell();
    var newTd2 = newTr.insertCell();
    var newTd3 = newTr.insertCell();
    //设置列内容和属性
    newTd0.innerText = document.all("a").options[document.all("a").selectedIndex].text;
    newTd1.innerText = document.all("b").value;
    newTd2.innerText = document.all("c").value;
    newTd3.innerHTML= '<input type="button" name="del" value="删除" οnclick="del(this)">';
}
function del(o){
    //获取表格
    var t=document.getElementById('testTbl');
    //删除当前行
    t.deleteRow(o.parentNode.parentNode.rowIndex)
}
</script>
</body>
</html>

//动态添加行
function addRow(){
  var table = document.getElementById("tableID");
  var newRow = table.insertRow(); //创建新行
  var newCell1 = newRow.insertCell(); //创建新单元格
  newCell.innerHTML = ""； //单元格内的内容
  newCell.setAttribute("align","center"); //设置位置
}
//动态删除行
function deleteRow(){
  var rowIndex = event.srcElement.parentElement.parentElement.rowIndex;
  var styles = document.getElementById("tableID");
  styles.deleteRow(rowIndex);
}

用克隆的方式

<html>
<head>
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript">
var index = 0;
$(document).ready(function(){
 $("button").click(function(){
 index++;
  $("body").append($("p").clone().attr({'id':'name'+index,'name':'pwd'+index}));
 });
});
</script>
</head>
<body>
<p>This is a paragraph.</p>
<button>复制每个 p 元素，然后追加到 body 元素</button>
</body>
</html>

下面是直接添加和删除当前table表格,很好用
