The title alone would probably result in a chanting "NO!" as the popular answer, but please let me elaborate.
We have a table of items that represent something. Each item can hold one to five attributes. A column in the table displays how many attributes each item has. This column consists of a cell for each item, containing a link-styled label saying 1, 2, 3..., depending on how many attributes it has. If the user hovers over the cell, a tooltip will appear displaying a text with the ID's of the attributes contained in this item.
The label, styled as a link, is not clickable as it ignores any click input. The reason for its appearance as a link is to attract the user to it, potentially leading to the user thinking "Hey, I have something here". They might hover over it, perhaps try to click it, and will be shown the tooltip.
I'm not really sure how else to communicate affordance for a tooltip.
Would this be considered good UX? You could argue that the user is being fooled, but is the gain enough to justify that?
Own opinions are OK but I would prefer factual evidence strengthening your case.
EDIT : I guess a side question here is whether it's OK to have a tooltip for something that isn't an action but a display of data instead?
