I'd use a grid widget to display a matrix, eg.:

I'd want something that was convenient to navigate and could manage large datasets efficiently. For example, a matrix could be a lookup table on a 16 bit RGB image, so you'd need 3 columns by 65k rows. I have a bunch of 13 channel 16 bit images so obviously tables get even larger there.

I used GtkSheet previously but I've not tried the gtk2 version of that yet. GtkSheet used to be limited to sheets of 32k pixels by 32k pixels, maybe they've fixed that.
