Canvas inside cell

[Ex glider pilot]

Hi New to HandsonTable and this group. Is it possible to draw inside a cell as if it were a canvas please? So for example within a row of cells I might draw a different colour circle in each cell? I know that there may be other ways to do this: eg adding an image of a circle, but I don't want to go that route. It would be great if there were a jsfiddle example out there, tried googling but no luck.
