How can I remove the data from these boxes so that only a 20x15 table in the
same order as this would be if the boxes were removed?

This is still the most convincing argument for changing RGB to GrB.
The values from dark to light are correct.

The top portion of the image is all very dark, but there are some very large
numbers in the top portion of the data. The first column (red) is the more
valuable than the second column (green) so the pattern does not preserve
value (light and dark)
