The option TableSpacing adjusts spacing. The default is Automatic, which on the
Mac is {1,3, ....} and gives one blank line between rows and a minimum of 3
spaces between columns. If you use

 MatrixForm[Table[x,{3},{50}], TableSpacing -> {0,1}] 

you get no blank lines between rows and just one space between columns. You may
also need to set the the Right Margin to -20 ....

Unfortunately, if some entries in a matrix are big then because MatrixForm
generates uniform spacing you can get a lot of unwanted space around small
entries. To deal with this use TableForm instead of MatrixForm, this does not
use uniform spacing (the same options are available).
