convert a cell of a Table to hyperLink

I am doing multi-row save inside vaadin table.After successful save , i want to convert only 1 spacific column to a hyperLink.
I am using tableFieldFactory to generate multiple rows.HowEver i am not able to convert the spacific column to a hyperLink.
I know one option is to set a hyperLinkGenerator for that spacific column . Unfortunately if i add a hyperLinkGenerator ,then the spacific column for which i add HyperLinkGenerator() ,is getting blank .MoreOver the sapcified row is a comboBox And the vaadin verison is 7.x.

Any suggestions or any spacific sample code .please guide me.
