Appending to the rows of a table

Question

I have a two dimensional list and a one dimensional list. I would like to insert the 1D list into the 2D list as an additional column. For example:

array = {         


        

Answer 1

Here is my try using Join

In[11]:= Join[array,List/@column,2]
Out[11]= {{a,1,2,x},{b,2,3,y},{c,3,4,z}}

It might be comparable to the fastest one among previously mentioned programs.
