### MappedTable
|
|
|
|
Renders a table with rows dynamically created from an array of data.
|
|
|
|
Use the value of the `headers` prop to conditionally render a table with a header. Use `Array.prototype.map` to render every item in `data` as a `<tr>` element and give it a `key`. `data` can either be an array of objects with the `id` and `name` properties or an array of primitives. Omit the `headers` prop to render a `table` without headers.
|
|
|
|
```jsx
|
|
function MappedTable({ headers, data }) {
|
|
return (
|
|
<table>
|
|
<thead>
|
|
{headers && (
|
|
<tr>
|
|
{headers.map((h, i) => (
|
|
<th key={i}>h</th>
|
|
))}
|
|
</tr>
|
|
)}
|
|
</thead>
|
|
<tbody>
|
|
{data.map((v, i) =>
|
|
(
|
|
<tr obj={v} key={v.id || i}>
|
|
<td>v.id</td>
|
|
<td>v.name</td>
|
|
</tr>
|
|
);
|
|
)}
|
|
</tbody>
|
|
</table>
|
|
);
|
|
}
|
|
```
|
|
|
|
```jsx
|
|
const people = [{ id: 841, name: 'John' }, { id: 241, name: 'Jesse' }];
|
|
const headers = ['id', 'name'];
|
|
ReactDOM.render(
|
|
<MappedTable data={people} headers={headers} />,
|
|
document.getElementById('root')
|
|
);
|
|
```
