I just realized that there is another approach to producing a nice 
graphic object representing a table or even a matrix. You need to pay 
attention to the FormatType option in the Text primitive.

Here is another version of the graphic below, thsi time we will 
represent out table as a matrix wiht the usual matrix brackets.





There are lots of variations onthsi theme you can try and you can of 
course make, if you wish, use of the options available in Text.
