I have a use case wherein upon expansion of a child node, in the space where a new row would normally be created, I need an <div> of content expanded down and across the width of the table. This functionality can be seen in action with the jQuery plugin DataTables (https://www.datatables.net/). How would I go about doing this with the TreeTable component?
I've looked into applying a column body template, but that only applies to the cell of each respective column. If this feature isn't obtainable, I will gladly add it as a feature request, something like DataTable row group would probably do the trick.
