Here is the scenario: I have a dataTable and I need a toolTip to appear when someone mouses over an entry in a column. I looked at the examples and it seems as if they are preloading the tooltip as the dataTable is generated. I would like the load to occur when the user upon mouseover. I could be wrong, is this preloading? If I am not wrong, could someone provide examples on how to pull the tooltip from the database on column mouseover? Basically, I want to pull the information that appears in the toolTip when the user mouses over the column they are interested in. I dont understand how this is occuring in the car example in the live demo.
