html - 在一个table表单中 td用v-for 使用v-if判断是否显示然后用一个外部的button 判断点击最后一行隐藏

手机用户2502875921 发布于 2022-11-03 15:26

button

问题大概如题目描述的那样
也就是 v-for循环出来的 td
然后点击外部一个button 让其中一个td隐藏这个怎么实现
就是绑定

如图也就是说点击按钮“减少了”只将“回来了”这一列隐藏点击再显示





    
    
    




    
        

            
                
                    
                        {{ col.name }}
                    
                
            
            
                
                    
                        {{ entry[col.key] }}
                    
                
            
        
        
        
        {{ checked }}

{{ col.name }}
{{ entry[col.key] }}

<tr v-for="(index,entry) in items">
    <td v-for="col in columns" v-show="col.key == 'AREA_ID'?:'backon':''">
        <span v-else>{{ entry[col.key] }}</span>
    </td>
</tr>

这样就可以咯

按钮 @click="backon = !backon"

文民左

自己实现了
用v-bind绑定了类
可能不是最优
