## JSON字段存储
- 实现表单组合并到指定的字段中，并以JSON格式存储
- 表单模式：JSON指定模式和field指定模式
#### 示例效果：路径/ht/json
数据设置
```
<?php
return [
'type' => 'sql',
'method' => 'list',
'config' => [
'table' => 'json'
],
];
```
列表设置
```
<?php
return [
'field' => [
'id' => [
'width' => 150,
'fixed' => true
],
'data_1' => ['width' => 50],
'data_2' => ['width' => 50]
],
'handle' => [
'hobby' => [
'name' => '兴趣爱好',
'type' => 'selects',
'from' => [
'hobby',
'id',
'name'
],
'json' => 'data_1', // JSON数据保存到字段data_1中，键为hobby
],
'email' => [
'name' => '邮箱',
'json' => 'data_1',
],
'mobile' => [
'name' => '手机号',
'json' => 'data_1',

'type' => 'radio',
'list' => [
'a' => '科学家',
'b' => '发明家',
'c' => '程序员',
],
'json' => 'data_1',
],
'data_2' => [
'type' => 'field', // 字段类型，把key-value保存到data_2字段中，并以JSON数据格式存储
'field' => [
'name' => '昵称',
'star' => '偶像',
'music' => '歌曲'
]
]
],
'handleinfo' => [
'ismax' => true
],
'is' => [
