如果您有唯一標識符（如 id）并且只想允許一次編輯一行，則可以將edit變量設置為id當前正在編輯的行的 。
您還可以使用通用槽v-slot:cell()來減少編寫的模板數量。
例子
new Vue({
el: "#app",
data() {
return {
edit: null,
employees: [{
id: 0,
employeeName: "Jane",
joinDate: "11-11-1111",
selectedDepartment: "IT",
jobDescription: "Nerd"
},
{
id: 1,
employeeName: "Peter",
joinDate: "12-12-1212",
selectedDepartment: "Accounting",
jobDescription: "Moneier"
}
],
fields: [{
key: 'employeeName',
label: 'Employee Name',
sortable: true
},
{
key: 'joinDate',
label: 'Join Date',
sortable: true
},
{
key: 'selectedDepartment',
label: 'Selected Department',
sortable: true
},
{
key: 'jobDescription',
label: 'Job Description',
sortable: true
},
{
key: 'actions',
label: 'Actions'
}
]
}
},
computed: {
rows() {
return this.employees.length
}
},
methods: {
onEdit(id) {
this.edit = this.edit !== id ? id : null;
}
}
})

<template v-if="edit != item.id">{{ value }}</template>
<b-form-input v-else v-model="item[key]" />
</template>
<template v-slot:cell(actions)="{ item: { id }}">
<b-dropdown variant="primary" text="Actions">
<b-dropdown-item @click="onEdit(id)">{{ edit === id ? 'Save' : 'Edit' }}</b-dropdown-item>
<b-dropdown-divider></b-dropdown-divider>
<b-dropdown-item @click="onDelete(id)">Delete</b-dropdown-item>
</b-dropdown>
</template>
</b-table>
</div>
如果您沒有每行的唯一標識符，或者希望能夠一次編輯多行，您可以向您的項目添加一個標志（在示例中），這將切換isEditing當前是否正在編輯該行或不。
