Clear previously generated DOM <td> by id

Hi,
First i need to ask about generated HTML!!!
I am using Firefox and shift-k gives me the console. Then clicking on the inspector gives me the uptodate HTML. But I can’t see it all in one go I have to keep expanding every element. Is there any way to do display all the html without having to go through every element?
The problem is that each of these little left arrows have to be clicked on to expand the HTML. Is there any way to just view it all?

I know there is already a sitepoint thread on this question.
Thanks
