select

clearable 清空默认值可以为null吗，不是“”。往后端传数据传“”会有问题，所以只能传null。

Can the clearable clear default be null, not ''. There will be a problem in sending data to "" from the back end, so only null can be passed.

。。。。后端处理

这明显是设计缺陷，一般后台mybatis是依据 值是否 为null，有则传入，无则不筛选的。 其他ui框架比如ant design 也是 clearable 后为null。 我真的很不理解element 为什么自作主张把清空改为空字符串，真是逗了，前端大佬的思路都那么清奇的吗，好逗

不止select，input输入也是变成‘’，element这么沙雕的操作，真的想弃用了。。。

一般Select框都是或者有值，或者就直接为null，空算个毛线意思啊
