add checkboxes to a specific column using javascript or jquery while displaying a table

I am displaying data in a table like this:

name country place number
ashwin India delhi 123
sita India Ajmer 456

and so on.
i want to add checkboxes on hover to a column and allow the user to be able to select multiple values for that column.eg the user can select delhi and ajmer or just delhi.

please help with some jquery or javascript code for this? Thank you.
