DIV table colspan: how?

Question

How do I achieve colspan/rowspan behavior in tableless (e.g. div.table {display: table;} div.tr {display: table-row;} etc.) table?

Answer 1

I would imagine that this would be covered by CSS Tables, a specification which, while mentioned on the CSS homepage, appears to currently be at a state of "not yet published in any form"

In practical terms, you can't achieve this at present.
