我是靠谱客的博主开放铃铛，最近开发中收集的这篇文章主要介绍vue+element的表格中添加加减按钮的问题，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

闲话少说先上效果图：

在这里插入图片描述
就是加减按钮能点，而且互不影响点击的效果。

起关键作用的就是在vue中的一个点击事件的控制：
@click.prevent=" "

而加了这个是只能点击一次：
click.self.prevent=“”

上代码：HTML

 <!DOCTYPE html>
    <html>
    <head>
        <meta charset="utf-8" />
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <title>Page Title</title>
        <meta name="viewport" content="width=device-width, initial-scale=1">

             .el-table thead {
             color: #fff;
             }
            
        </style>
    </head>
    <body>
        <div id="apps">
            <el-table :key="tableKey2" height="200" :data="tableData"  border fit
                highlight-current-row style="width: 800px;min-height:380px;" :header-cell-style="{background:'#199ED8'}">
                <el-table-column align="center" type="index" label="序号" width="50">

                </el-table-column>
            </el-table>
        </div>
        
    </body>
    <script src="https://cdn.bootcss.com/vue/2.5.1/vue.min.js"></script>
    <script src="https://cdn.bootcss.com/element-ui/2.3.9/index.js"></script>
    <script src="/tableop.js"></script>
    </html>

js部分：

 var apps = new Vue({
      el: "#apps",
      data(){
        return{
            tableData: [{
                date: '2016-05-02',
                name: '王小虎1',
                number:0,
                address: '上 1518 弄'
            }, {
                date: '2016-05-04',
                name: '王小虎2',
                number:0,
                address: '上海  弄'
            }, {
                date: '2016-05-01',
                name: '王小虎3',
                number:0,
                address: '上弄'
            }, {
                date: '2016-05-03',
                name: '王小虎4',
                number:0,
                address: '上 弄'
            }],
            tableKey2: 0,
        }
      },
        created(){
        },
        methods: {
            addRow(row){
            //   console.log(row)
                row.number = row.number + 1
            },
            delRow(row){
            //   console.log(row)
                if (row.number != 0) {
                    row.number = row.number - 1
                }
            }
        },
    });
