Vue中实现拖放排序，啥也不说，贴上代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<style>
ul {
min-height: 100px;
width: 200px;
margin: 20px auto;
background: #eee;
}
li {
min-height: 2em;
margin-top: 10px;
background: #abcded;
}
/ 组件过渡类 /
.drog-move {
transition: tr
