前言

经过几个月的构思与挣扎，终于把低代码平台的表格与列表的CRUD部分撸出来了，废话不多说，一起来看看吧。

为便于大家理解，接下来我分几个部分来介绍低代码：

1、拖拉拽组件生成表单

2、输出表单json串

3、配置表单

4、配置列表

5、配置菜单

6、列表数据的展示以及增删改查

一、表单拖拉拽

这里引入的是VFROM的表单设计器和渲染器，具体使用方式可以网上查一下VFROM表单设计器，根据业务需求拖拉拽生成一个个人简历的表单

二、输出表单json串

点击导出按钮，将json串复制出来，创建表单时作为json字符串输入，用于后续渲染表单

下方为表单的代码

],

"layoutType": "PC",

"onFormCreated": "",

"onFormMounted": "",

"onFormDataChange": "",

"jsonVersion": 3,

}

}

三、、配置表单

创建一个表单，填写相关信息，将上一步导出的json串复制到新增页面的最后一个json串字段后，点击保存按钮，生成对应的表格对象

可在列表查询对应的数据对象

打开该表单页面地址可以看到如下：

填写信息后即可保存

四、配置列表

表单生成完成后，需要创建一个列表配置；将该表单通过了列表的形式挂载为一个菜单

配置列表表头

[{

key: '1',

label: '创建人',

prop: 'CREATED_BY',

width: '150',

headerAlign: 'center',

align: 'center',

scope: false,

sortable: true

},

{key: '2',

label: '创建时间',

prop: 'CREATED_TIME',

width: '150',

headerAlign: 'center',

align: 'center',

scope: false,

sortable: true

},

{

key: '3',

label: '姓名',

prop: 'input111043',

width: '150',

headerAlign: 'center',

align: 'right',

scope: false,

sortable: true

},

{

key: '4',

label: '年龄1',

prop: 'number84077',

width: '150',

headerAlign: 'center',

align: 'right',

scope: false,

sortable: true

},

{

key: '5',

label: '简介',

prop: 'textarea99146',

width: '150',

headerAlign: 'left',

align: 'left',

scope: false,

sortable: false

}

]
