Table表格添加,删除行

最近需要表格添加删除行,添加行简单,删除行就有点儿懵逼了,于是网上找实例,功夫不负有心人,终于让我找到了,下面的是代码,大家觉得可以,记得点赞哦!!!谢谢!
需要的拿去,转载请在明显的位置标注出出处!!! 

<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" onclick="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 type="text/javascript" src="jquery-easyui/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
