这段代码是一个 Vue.js 组件中使用 Element UI 组件库进行渲染的模板代码。它使用了 Vue.js 3 中的解构插槽语法,并结合了 Element UI 组件的特性来实现一个用户列表的操作界面。
具体来说,这个模板中包含了三个操作按钮,分别是“分配角色”、“编辑”和“删除”。这些按钮的点击事件都会触发组件中对应的方法,以完成相应的操作。
这个模板的核心在于 `template` 标签中的 `#="{ row, $index }"` 属性。这个属性使用了解构语法,将插槽内容解构为一个对象并命名为 `row` 和 `$index`。这个对象中包含了当前循环的数据和索引,可以在插槽内容中使用。
在插槽内容中,使用了 Element UI 中的 `el-button` 和 `el-popconfirm` 组件来渲染操作按钮。其中,`el-popconfirm` 组件是一个弹出确认框,当用户点击“删除”按钮时,会弹出一个确认框来提示用户是否确定要删除该用户。
总的来说,这段代码实现了一个用户列表的操作界面,让用户可以方便地对列表中的每个用户进行编辑、删除和角色分配等操作。

需要注意的是,Element UI的CSS样式需要在HTML文件中引入。此外,上述代码中的`activeName`、`search`、`filterTableData`、`handleEdit`和`handleDelete`需要在JavaScript中定义和实现。
<el-table-column align="right" width="250"> <template #header> <el-input v-model="search" size="small" placeholder="Device to search" style="width: 50%;" /> <el-button circle> <el-icon> <Search /> </el-icon> </el-button> </template> <template #default="scope"> <el-button type="info" round size="small" @click="handleSearch(scope.row)">查看</el-button> <el-button size="small" round type="info" @click="handleDelete(scope.$index, scope.row)">卸载设备</el-button> </template> </el-table-column>解释代码
这是一个使用了 Element UI 组件库的表格组件 el-table-column,其中包含了两个模板: #header 和 #default。
#header 模板包含了一个 el-input 组件和一个 el-button 组件,用于实现搜索功能。el-input 组件通过 v-model 双向绑定了一个变量 search,el-button 组件包含了一个圆形按钮和一个搜索图标。该模板被用作表格列的表头。
#default 模板包含了两个 el-button 组件,用于实现查看和卸载设备的功能。这些按钮通过 @click 监听了两个方法 handleSearch 和 handleDelete,这些方法将在用户点击按钮时被调用。该模板被用作表格列的内容。
其中,scope 是一个作用域插槽对象,用于提供当前行的数据和索引等信息,可以在模板中使用。
