It would be great if could add a function to add the header in the stack mode. I think @best6699 means that the header row would be shown not above the other rows (with content) but next the (content) rows and repeat for every (content) row.
Like this:
Header row – Content row
Header row – Content row
Header row – Content row
So we would create a stack table with 2 columns.
Is this somehow possible to do with CSS?
