html - 在一個table表單中 td用v-for 使用v-if判斷是否顯示 然后用一個外部的button 判斷點擊最后一行隱藏
問題描述
問題大概如題目描述的那樣也就是 v-for循環出來的 td 然后 點擊外部一個button 讓其中一個td隱藏 這個怎么實現就是綁定
如圖 也就是說 點擊按鈕“減少了”只將“回來了”這一列隱藏 點擊再顯示

問題解答
回答1：vue 最后的td添加v-show=‘st’ button綁定click 控制st的值為true false
回答2：自己實現了用v-bind綁定了類 可能不是最優

這樣就可以咯
按鈕 @click='backon = !backon'
