@zhuravel I found out that introducing tag_options instead of column[class] can not be done without backward incompatibility, so we have to do it in the PR.

The problem I wasn't able to solve is the merge of class attribute. In current implementation, using tag_options: {class: "my-class"} would cause the override of datagrid-order-active-asc/desc classes. That is not easily solvable as class maybe specified as String, Hash or Array. I didn't find universal utility to merge two class options of tag.whatever.

That is not easily solvable as class maybe specified as String, Hash or Array.

You might try to delegate that to class_names method added in Rails 6.1:

Either way no problem, I’ll migrate to only use tag_options.
