Using HTML in title attribute


I’m trying to format the title attribute of a cell in the grid so that when the user hovers they get a formatted table rather than just a straight line of text.
Something like:

       {  id:1,
            {value: "John Thomas","title": "<table><tr><td>Some</td></tr><tr><td>text</td></tr></table>"},

Is it possible? Thanks


The default title is a staight text. You may try to display your own custom popUp instead of the title with the needed formatted content from the onMouseOver event:
