Adding Slugs to table cells

I’m just wondering if it could be possible to add slugs to the content in a table cell in order to change that cell’s appearance when rendering. For example, I have a cell that I want to have a red background and I will have multiple copies of that table, but the cell(s) with a red background would differ so I’d like to put something in the cell like ~redcell~ and have that rendered as a class added to that particular cell like <td class=”redcell”>. I was thinking the same for adding a tooltip with something like $$Tooltip Text Here$$ and have it render with the title attribute for the cell. I have some php background and had a peek in the code but I’m just wondering how straightforward this would be to implement…on the surface it seems similar to the #colspan# slug already in use.
