Acutally, I think that observation leads to a solution for the first set, along with the fact that each row contains the same number of -s and |s. If you map the values 0-9 to each row, the next row is a simple rearrangement.

0123456789 in one row maps to
2056789341 in the next row.

To be more precise, the first character in each row is the third digit in the previous row, the second digit in each row is the first digit of the previous row, the third digit is the sixth digit of the row above it, and so on.

I was unable to determine a similar 1:1 mapping for the second series, and Gamer's comments seem to imply that each set has different properties.

This solution works just as well as the one I came up with before, for the small sample we have, but both still have the problem that the symbols in the first row appear to be completely arbitrary.
