I have got a table that I would like to adorn with some coloured rings to pick out some overlapping subsets of its elements. The table itself consists simply of a rectangular array of numbers. I was wondering whether I could make it in a graphics program, do the adornment there, save it as an image (e.g. a .pdf), and then call it from Texmaker as a table. It needs to be numbered e.g. 'Table 5'.
The idea is that from the reader's point of view, it would be a table in the same way as any other.
I'd be grateful if someone could advise on whether this is possible, and if so, how to do it.
Many thanks in advance! Harry
