    <!-- 2. 根据结构和数据创建表格并加删除功能

    指定的结构：  -->
    <table border=1 width="500">
        <thead>
            <tr id="a">
                <th>序号</th>
                <th>姓名</th>
                <th>年龄</th>
                <th>性别</th>

                <th>操作</th>
            </tr>
        </thead>
        <tbody>

        </tbody>
    </table>

<script>
    //删除表格
    var arr = [
        {        
        name:"令狐冲",
        age:20,
        sex:"男",
        skill:"独孤九剑"
        },
        {
        name:"东方不败",
        age:50,
        sex:"女",
        skill:"葵花宝典"
        },
        {
        name:"任我行",
        age:55,
        sex:"男",
        skill:"吸星大法"
        }
    ]
    var tbody = document.querySelector("tbody");
    loadHTML()
    function loadHTML(){
        var str ='';
        for(var i=0;i<arr.length;i++){
            var obj = arr[i]
            str +="<tr><td>" + (i+1) +"</td><td>" + obj.name + "</td><td>" + obj.age + "</td><td>" + obj.sex + "</td><td>" + obj.skill + "</td><td>" + "删除" + "</td></tr>"
        }
        var tbody = document.querySelector('tbody');
        tbody.innerHTML = str;
    }
    
    addEvent()
    function addEvent(){
        //获取删除的td
        var tds = document.querySelectorAll('td:last-child');
        for(var i=0;i<tds.length;i++){
            (function(i){
                tds[i].onclick = function(){
                    arr.splice(i,1)
                    loadHTML()
                    addEvent()
                }  
            })(i)
        }
    }
</script>
