官方支持多级表头，只需要嵌套列就行，但是场景受限

这里需求是表头有一部分是动态变化的，其他部分是固定的，通过自定义组件实现。

效果如下：

组件

表格和列：

windows命令

• 查看当前所有的tcp连接netstat -ano
• 查看所有8080端口的tcp连接netstat -ano |findstr "8080"
• 查看所有的“TIME_WAIT”状态的tcp连接netstat -ano |findstr "TIME_WAIT"
• 统计time_wait出现的次数（按行统计） /i 忽略大小写netstat -ano |find /i /c "TIME_WAIT"

设置TIME_WAIT的自动关闭时间（默认4分钟）和可用端口个数

• 运行/cmdregedit进入注册表
• 进入HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Tcpip/Parameters
• 新建 DWORD 类型的注册表项，命名为：TCPTimedWaitDelay，值数据： 30（TIME_WAIT的自动断开时间，默认为4分钟）

全局设置Select下拉菜单列表样式

1、全局样式element-ui.css中设置下拉列表固定宽度，当Select下拉菜单宽度大于这里设置的宽度时，会自动显示三个点

.el-select-dropdown {
    width: 200px;
}

2、main.js中引入全局样式

import './assets/style/element-ui.css'
