We can make the list of all primes:

a(m,n+1) is the smallest prime of the form a(m,n)*2^k+1 (k>=0)

a(m+1,1) is the smallest prime not in the first m rows

Code:
 2     3      7       29           59   1889   3779   7559
 5    11     23       47   47*2^583+1
13    53    107      857         6857
17   137   1097   140417
The first row of this table is indeed A084435.

For the Riesel analog:

a(m,n+1) is the smallest prime of the form a(m,n)*2^k-1 (k>=1)

a(m+1,1) is the smallest prime not in the first m rows

Code:
 2    3      5    19        37   73   9343
 7   13    103   823   1685503
11   43   5503
17   67   2143
