Template based column definitions

[buschtoens]

Column definitions were put into JS land, because Ember and Handlebars lacked some important features regarding flexibility and composability. But the landscape is slowly shifting towards a shiny new future with one major advancement being the fantastic Named Blocks RFC 226 by @machty. ☀️ ✨

The ultimate goal is to remove the need for the columns array and instead define the columns in the template. Maybe we'll also be able to remove the need for Table objects.

This issue is meant to serve as a brain dump and constant reminder. If you have ideas, wishes, questions or anything else related to this, please do add a comment! 😊

It's a good idea, but I would imagine the feature needs to exist side-by-side with data-driven column definition. How else can you persist the column reordering?
