How does (SIC) assembler print hash tables?

Question

I am trying to make an assembler in C for the SIC architecture. And I saw that symbol table and object code table are usually made with hash tables.

What I wonder is, how assemblers print these tables.

1. Do they memorize the insertion order of those hash tables?
2. Or do they just print it by using intermmediate file?

And if it is the first case, how can I implement that in C?

I tried to search it in Internet, but it was no avail.
