代码比较多，能简单描述下你的思路吗

代码比较多，能简单描述下你的思路吗

这边的思路就是将所有是用户选择的表单组件列举出来，使用tableForm.selectPlaceholder，而其他的使用tableForm.inputPlaceholder，而针对范围选择的组件，我们使用数组，其他则直接使用相应的placeholder

[chenshuai2144]

你怎么知道用户的是什么，我觉得不如简单点，不要给用户传 placeholder

[kiner-tang]

你怎么知道用户的是什么，我觉得不如简单点，不要给用户传 placeholder

这个只是默认的placeholder呀，用户可以自己传placeholder覆盖的呀，只有用户没传placeholder的时候才会使用这个逻辑

[kiner-tang]

按照目前线上的逻辑，如果用户不传placeholder的话，有些类型是会显示异常的，比如树形选择框没显示placeholder 以及范围选择框异常

[chenshuai2144]

我们自己的自己处理吧，用了renderForm 就不要给 placeholder props 了。

树形选择框没显示placeholder，这个是个bug，应该修复一下

[chenshuai2144]

这个issue的问题就是应该给 placeholder 数组的时候给了一个 placeholder。导致显示异常。还不如不显示

[kiner-tang]

这个issue的问题就是应该给 placeholder 数组的时候给了一个 placeholder。导致显示异常。还不如不显示

不是吧，我理解是这边显示的是一个范围选择器，应该传一个placeholder数组过去，但issue给的示例没有传自定义的placeholder,那么就应该采用默认的placeholder，但我们以前的逻辑，默认的placeholder不是数组，并且固定成了tableForm.inputPlaceholder，所以导致显示异常了。

我们没法知道用户 renderFormItem 到底给的是什么的，可能是个input 可能是的daterange

[kiner-tang]

我们不是应该根据用户显示指定的valueType判断类型吗？而且我们这里设置的也是默认placeholder，如果用户一定要在renderFormItem里传一个与valueType相悖的组件，那么用户自己自定义placeholder是不是也可以？

我也觉得应该如果传了 renderFormItem 的话应该交给用户自行维护 placeholder，如果用户没指定，则用组件的默认行为而不是统一注入。这里有个类似的 issue。

[kiner-tang]

那当用户传入renderFormItem时，我们不指定默认的placeholder,如果没传入的话，我们就按照这个PR的方式处理一下默认的placeholder如何？ @chenshuai2144

看起来已经好了，能合并了吗

[kiner-tang]

看起来已经好了，能合并了吗

恩恩，已经按照要求，传入renderFormItem时不指定placeholder，并且为各个原子组件，没有默认placeholder的，都添加上了默认的placeholder了

先稍等一下，我再最后检查一下有没有错漏的地方

[kiner-tang]

@chenshuai2144 应该没问题了
