The most primitive way imaginable: with MS Paint.
1) PrintScreen the upper half of the crosstable
2) Paste it into Paint. You will see there should be room left to the bottom
3) PrintScreen the lower half of the crosstable
4) Paste it into the same image in Paint, it's OK if it overlaps the upper half a bit
5) Select a portion of the lower half, with the upper border preferably in blank space between two engine entries
6) Drag the selection upward and superimpose it on the upper half.
7) Crop and save
Steps 5 and 6 can be a bit tricky. If the table is long enough you may need to zoom out, which makes perfect alignment of the two halves hard to achieve.
I imagine it should be a lot simpler with any half-decent image-editing program, like the ancient Paint Shop Pro I have on the old WinXP box and too lazy to install on this one. For starters, it can screencap just a program window, rather than the whole desktop; you can grab the crosstable at a high res to fit into one screen and resize the grabbed image with negligible quality loss.
Another solution is to test fewer entries, with more games per entry.
