The docs says that you cannot use empty string value for value field. As long as this is eventually acceptable, there is an issue, because for some reason null value also does not work. These both totally break my communication with backend service, because it seems I'll have to find and replace the values before saving (I do want to save null).

复现步骤

运行项目后点击跳转到详情页，然后返回首页。然后触发子组件的 onClick 事件时，回调函数却还是详情页的函数。去掉id属性后正常。

期望结果

有无id属性都应正常

实际结果

有id属性异常

While I try to change header titles by passing array of titles to options like below it does not override the headers. Instead it writes new headers first and original data with old headers again from next cell.

I am experiencing the same problem.

In addition, sheets js is mutating the header array passed in, which is not something I would ever expect.

Example:

const head

The documentation of all components lists the props as well as their usage. It would be great if we arrange the props list alphabetically to make it easier to find the required props.

Just like the expo docs and others.

In https://github.com/typescript-cheatsheets/react#useful-react-prop-type-examples it says

export declare interface AppProps {
  children: React.ReactNode; // best, accepts everything
}

ReactNode produces a false positive type check for {}.
