[OS X TeX] Cancelling columns?

I apologize for what is probably a simple thing, but it's defeated me  
for a while now.

I am writing a small note about calculation of determinants using  
minors. I would like to draw explicitly a line through the numbers of  
a row (which I think I can do with the ``soul'' package.) But how to  
do it with a column? If worse comes to worse, I can use LaTeXiT to  
export the matrix to Illustrator, draw the lines in Illustrator, and  
then use it as a graphic. But if LaTeX will do the job, I'd prefer that.

Many thanks in advance,
