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.
