Hi,
I am not sure what type of code you have tried. Plz try below code and let me know if you still facing any issues
$(".DivClassname").tooltip();
DivClassname is the Div you can store the initial value on the page load and for every mouse over on the table row tool tip will show.
Refer this below example for how to use the JQuery Tooltip.
