解释这行代码<el-table-column label="操作" width="150" key="operate" v-if="!depotId">

这行代码是Vue.js中的代码,用于渲染一个表格列,其中"操作"是这一列的标签,"width"定义了这一列的宽度,"key"是这一列数据的键名。其中的"v-if"是Vue.js中的条件渲染指令,用于判断是否需要渲染这一列,当条件为真时,这一列会被渲染出来,否则会被隐藏。在这个例子中,当"depotId"不存在时,这一列才会被渲染出来。

你提供的 'tomcat-users.xml' 文件是一个示例文件,其中包含了一些注释和示例用户角色和用户的声明。你需要根据你的需求对其进行修改。
如果你想要使用示例中的某个用户角色和用户,你需要取消相应部分的注释,并设置适当的密码。例如,如果你想要使用示例中的 `admin` 用户作为 `manager-gui` 角色的用户,你可以将以下行的注释取消,并将 `<must-be-changed>` 替换为你自己的密码:
```xml
<!--
<user username="admin" password="<must-be-changed>" roles="manager-gui"/>
-->
```
同时,如果你想要使用其他示例用户角色和用户,你可以按照相同的方式取消注释并设置密码。
如果你想要定义自己的用户角色和用户,你可以按照以下格式添加新的 `<role>` 和 `<user>` 元素:
```xml
<role rolename="your-role-name"/>
<user username="your-username" password="your-password" roles="your-role-name"/>
```
确保将 `<your-role-name>`, `<your-username>`, 和 `<your-password>` 替换为你自己定义的角色名、用户名和密码。
最后,保存并关闭 'tomcat-users.xml' 文件,并重新启动 Tomcat 服务器。这样你就可以使用修改后的用户角色和用户来进行部署和操作了。
