slot-scope
從 3.2.0 版本開始支持 slot-scope 寫法。
在 columns 的某列聲明 slot 后，就可以在 Table 的 slot 中使用 slot-scope。
slot-scope 的參數有 3 個：當前行數據 row，當前列數據 column，當前行序號 index。
示例可編輯表格
<template>
<Table :columns="columns" :data="data">
<template slot-scope="{ row, index }" slot="name">
<Input type="text" v-model="editName" v-if="editIndex === index" />
<span v-else>{{ row.name }}</span>
</template>
<template slot-scope="{ row, index }" slot="age">
<Input type="text" v-model="editAge" v-if="editIndex === index" />
<span v-else>{{ row.age }}</span>
</template>
<template slot-scope="{ row, index }" slot="birthday">
<Input type="text" v-model="editBirthday" v-if="editIndex === index" />
<span v-else>{{ getBirthday(row.birthday) }}</span>
</template>
<template slot-scope="{ row, index }" slot="address">
<Input type="text" v-model="editAddress" v-if="editIndex === index" />
<span v-else>{{ row.address }}</span>
</template>
<template slot-scope="{ row, index }" slot="action">
<div v-if="editIndex === index">
<Button @click="handleSave(index)">保存</Button>
<Button @click="editIndex = -1">取消</Button>
</div>
<div v-else>
<Button @click="handleEdit(row, index)">操作</Button>
</div>
</template>
</Table>
