Please add the ‘footer row’ options - similar to the ‘header row’. Now I can:
either leave it a regular row
or add a second header row - which is not exactly as I want to see it
Add a new switcher ‘footer row’ to a column row - just below the ‘header row’.
Use cases are pretty obvious: rows for Sum, Avg, Total, Conclusions, etc.
The alternatives are described above - just add a second ‘header row’ or accept the fact that this will be a common row.
This can also be implemented for columns (at the right side of a column) - see this feature request
Or maybe the whole feature of ‘header row/column’ can be reworked to allow visually select at what part of the table we want to stick a row/column (top, bottom, right, left). Then it will be independent of any specific locale and will fit for ‘right-to-left’ languages as well for example.
