It's a pretty common layout to have headline paragraphs in a separate column and their corresponding body paragraphs to the right. (See attached images for examples.) This layout is currently only supported by creating tables, but this isn't semantically correct for the content.

It would be great if InDesign supported assigning paragraph styles to specific columns, e.g. H1 spans columns 1-3, H2 is column 1, body copy spans columns 2-3.
