Perhaps it may be useful to make a quick summary of the three approaches
I proposed in answer to this question. The first method creates a bitmap
representation of the table of numbers or symbols, and while it does
scale, it looses quality, as bitmaps do. The second approach produces a
graphic representation of a table that can be scaled to an arbitrary
size and whose font can be changed by setting $DefaultFont to any chosen
font or size. However this method is less flexible: for example I think
one can't create matrix brackets using it. Finally, the last approach
produces a fixed size, fixed font graphic representation of a table.
