restricted divisors of the first 1000 positive integers

In the table below, the proper divisors (or restricted divisors) of the first thousand positive integers are listed in the right column. That is, given divisors $1,d_2,\mathrm{\dots },d_{k-1},n$, with $k$ being the total number of divisors and $d_k=n$, only $d_2$ through $d_{k-1}$ are listed in the table below.
