What are the next several lines and how are they formed?

Do the sequences have any special feature?

Does the pattern continue indefinitely?

I noticed that the number of elements in each row follows the prime numbers:
2, 3, 5, 7, 11, etc.

But so far, the pattern of the numbers themselves evades me. I can see several possibilities to generate the pattern so far.

Perhaps Bob will add a few more lines to help narrow down the possibilities.
