I have an idea how my feature could be implemented, and it consists of two parts.
- introduce a special row, or extend the "/" type used for colgroup and narrowing, to specify hidden (non-export) columns and special tag columns; - in that special row, there are two new special entries, say "T<" and "T>" which specify that the contents of each cell in that column should be exported into the <td> tag of the cell to the left or to the right. This way, the <td> tag can be set from within the table for each relevant cell. The only drawback is that all this is backend-specific, it only works for HTML, not for PDF in the way I've just described.
