前言
el-table二次封装请看 Element Plus二次封装el-table、可编辑表格
效果展示
可通过表单配置来决定哪些列展示或隐藏
代码
table.ts
const columnsData: any = [
{
prop: 'username',
label: '姓名',
show: true, // 通过 show 来控制列的展示或隐藏
},
{
prop: 'age',
label: '性别',
align: 'center',
type: 'status',
option: {
'1': '男',
'2': '女'
},
width: 80,
show: true
},
{
prop: 'phone',
label: '手机号',
align: 'center',
width: 150,
show: true
},
{
prop: 'email',
label: '邮箱',
align: 'center',
width: 180,
show: true
}
]

二级表头
二级表头其实没什么说的，嵌套一次循环就可以了
table.ts
const columnsData: any = [
{
label: '基础信息',
show: true, // 外层加了show属性
children: [
{
prop: 'menuPowerName',
label: '菜单权限名称',
min_width: 120,
fixed: true,
show: true
},
{
prop: 'menuPowerMark',
label: '菜单权限标识',
align: 'center',
width: 180,
fixed: true,
show: true
},
{
prop: 'menuName',
label: '所属菜单名称',
align: 'center',
width: 180,
fixed: true,
show: true
},
]
},
{
label: '时间',
show: true,
children: [
{
prop: 'createDate',
label: ' 创建时间',
align: 'center',
type: 'time',
width: 180,
show: true
}
]
}
]
index.vue
<!-- 嵌套一次循环 -->

这样就完成了，给大家看下效果
