从对象列表中逐行渲染 table

Render table row by key from list of objects

我正在尝试将我的数据绑定到 blueprint.js Table ,但是文档不清楚如何执行此操作。如何为 blueprint.js Table 创建自定义呈现函数以呈现对象列表中的键?

示例中默认为rowIndex

代码:

data = [
  { name: "L/S", col2: "abc" }, 
  { name: "HY", col2: "def" }
];

myRender = (rowIndex: number, key: string) => {
  return <Cell> {this.data[rowIndex][key]} </Cell>;
};

<Table numRows={2}>
  <Column name="not-working" cellRenderer={this.myRender("name")} />
  <Column name="not-working2" cellRenderer={this.myRender("col2")} />
</Table>;

错误:

TypeError
Cannot read property 'undefined' of undefined

  18 | 
  19 | myRender = (rowIndex: number, key: string) => {
> 20 |   return <Cell> {this.data[rowIndex][key]} </Cell>;
     |                                     ^
  21 | };

参见此处示例: https://codesandbox.io/s/k9l9q2150r

文档: https://blueprintjs.com/docs/#table.basic-usage

cellRenderer 需要一个以 rowIndex 作为参数的函数。所以这就是你需要做的:

myRender = (key: string) => (rowIndex: number) => {
  return <Cell>{this.data[rowIndex][key]}</Cell>;
};

这是 sandbox
