Umm, I'm not fully sure what you are asking, but I think the answer is:

    yes

Perhaps you could clarify?

Go to the store and buy the set of books 'Datastructures and Algorithms'
(or something like this) by Donald Knuth--read the section on hash tables. 
It addresses collisions in the table and many other things.  It just might
be the best purchase you ever make, in computer books. 

But to explain--when you have a collision in your hash table there are
many ways you can deal with it.  The only useful (imho) ways are chaining
from that point on.  Essentially, you drop a binary tree at each point
in the hash table, and just expand from there out--or simply a linear
linked list also works.  This is where the 'deep' reference comes into
play--where 'wide' is the width of the hash table and 'deep' is how deep
you want it to handle collisions.  Usually after you go so deep you
rebuild the table with a wider setting.
