We have a need for the Bryntum Scheduler to partition the grid up into groups. Scheduling was previously done by drawing up shapes on a powerpoint slide and taking a snapshot (see attachment). The Bryntum scheduler will replace this outdated workflow nicely, but making headers for categories would be incredibly helpful as the list of resources gets big.
Another way to put it is, essentially this is a category view, but with customizable row styling for the category headers.
See attachment for a mock up.

Have you seen our grouping demo, that's what we offer out of the box: https://bryntum.com/examples/scheduler-for-extjs/grouping

How do I customize the grouping header style like in the mockup image? And can I do this with the new library instead of the ExtJS library?
