Hello. If there is no heading in a column, what should be displayed? What about numbering? There is a very similar question in How to get the number of the first and last paragraph on a page and show the result in the header?.
#set page(header: [Heading 1#h(1fr)Heading 2], columns: 2)
#set par(justify: true)
= Heading 1
#lorem(50)
#lorem(60)
#lorem(70)
#lorem(80)
#lorem(50)
= Heading 2
#lorem(60)
#lorem(70)
#lorem(80)
#lorem(70)
Is this how it should look like?
