Formatting a particular cell in Webdynpro ALV

Hi,

I had developed a Webdynpro ALV Report. The report is sort of dynamic report and the headers are built inside the internal table itself along with the line items. I needs to use link to action for 1 column :

In above screenshot, I need to make the Substance Column as Link to Action. However the header part "Substance" should have format like the other column headers. As the Substance part is inside the internal table... it also changes to Link to Action. is there anyways I can change the format for that specific cell ?

Thanks and Regards
