tooltip for results in every cell

How to providing tool tip for the results in every cell?

For v.1 the tooltip example code is in /examples/grid/images.htm -

// add tooltips to the first column template and data model
    obj.getColumnTemplate(0).setAttribute("title", function(){return this.getItemProperty("tooltip")});
    obj.defineDataProperty("tooltip", function(i, j){return "Type: " + myData[i][2] + "\nDate Modified: " + myData[i][3] + "\nSize: " + myData[i][1]});
