Question

我正在尝试在Storybook https://storybook.js.org/

中呈现react-table组件

Error: Uncaught TypeError: Cannot read property 'map' of undefined
at decorateColumnTree (vendors~main.4c20d65610ba8d62ac56.bundle.js:210768)

在追究错误的根源之后，decorateColumnTree似乎收到了column参数的未定义定义。 https://github.com/tannerlinsley/react-table/blob/1d8ffb18f7afc862db5d4f1da5cfc6781ed10553/src/hooks/useTable.js#L166-L169

storybook version: ^5.1.9

react-table version: ^7.0.0-rf.15

好一会儿，我知道了。这主要是数据和变量作用域的问题。

最初，我是这样做的

import dummyData from './mockData'

table.addDecorator(withKnobs).add('Table', () =>
  React.createElement(() => {
    return (
      <Table
        columns={dummyData.columns}
        data={dummyData.data}
      />
    )
  })
)

但是，dummyData在React.createElement中未定义，所以我选择这样做：

table.addDecorator(withKnobs).add('NextTable', () =>
  React.createElement(() => {
    return (
      <MockTableComponent />
    )
  })
)

其中模拟数据和模拟列存储在呈现MockTableComponent的{{1}}中

使用Storybook进行React-table [v7]渲染
