新建表

这里我加了几个测试字段 createTime、remark、money

// 文档教程: https://uniapp.dcloud.net.cn/uniCloud/schema
{"bsonType": "object","required": [],"permission": {"read": true,"create": true,"update": true,"delete": true},"properties": {"_id": {"description": "ID，系统自动生成"},"createTime":{"bosnType":"string"},"remark":{"bosnType":"string"},"money":{"bosnType":"number"}}
}

效果
