widgetcolumn in grid not sortable by default but docs say it is

The docs say that widgetcolumn is sortable by default.

However, looking at the code and testing it out, the class defaults sortable to false.



There are other discrepancies with the widget docs, too. For example, the widgetcolumn doesn't even list widget as a valid config option - confusing if you're looking at the docs trying to learn about this new feature.
