Add ability to mass expand / collapse master-detail view

Similar to how you can specify a column for the selection, it'd be nice if you could specify a column for the expand / collapse column so that you can provide a header value and handle a header value click change event.

The idea being that I could mass expand or collapse master detail rows similar to how I can mass select rows.

Here is another approach for adding custom Expand/Collapse column (at any position) with the ability for customizing the cells and the headerCells:

Hello Ryan,

Thank you for submitting the feature request.

With the current implementation it is still possible to render custom expand/collapse column, but the default one must be hidden with CSS:

Another option would be to handle the headerCellRender and add the custom content for the default expand column (using the "field" value to determine the correct header cell):

Here is an example with the headerCellRender approach:
