I could tell you if it were possible if I had an idea of what you want to do when you query a cell in a table.
Are you imagining that you browse to a page on the web using a browser, and then mouse over a cell in a table on that page and see the name of the image?
Had a thought that your question gave form to. Thinking it could be done by maintaing a duplicate table and inserting a numeric code for the color that is placed in the same cell location as in the visible table. Does this sound rational?
Each cell would receive a red, green or yellow color based on a question asked when the user clicks on a cell to select a question. The color represents the accuracy of the response. At the end of a session the cells would be queried and a tally of each color is made to provide a subjective evaluation of the users responses.
Thank you for your patience with me.
It would certainly be possible to do that with PHP. But I'm not sure why there are colors involved instead of just a numeric value. Are there other reasons that you have selected what seems to me to be an awkward way to describe this progress?
Well, the answer is the same. You can do this with PHP or ColdFusion or dot NET or ASP or any server scripting. But there is no button to press to do it for you - you would have to have a good enough grasp of the scripting method to code it yourself.
