/**

*
|
|
* @description
|
|
* Plugin allows binding the table rows with their headers.
|
|
*
|
|
* If the plugin is enabled, the table row headers will "stick" to the rows, when they are hidden/moved. Basically, if
|
|
* at the initialization row 0 has a header titled "A", it will have it no matter what you do with the table.
|
|
*
|
|
* @example
|
|
* ::: only-for javascript
|
|
* ```js
|
|
* const container = document.getElementById('example');
|
|
* const hot = new Handsontable(container, {
|
|
* data: getData(),
|
|
* // enable plugin
|
|
* bindRowsWithHeaders: true
|
|
* });
|
|
* ```
|
|
* :::
|
|
*
|
|
* ::: only-for react
|
|
* ```jsx
|
|
* <HotTable
|
|
* data={getData()}
|
|
* // enable plugin
|
|
* bindRowsWithHeaders={true}
|
|
* />
|
