Change Edit Profile page

I need to change inner structure of edit profile page like table replace with div etc...

In which file i changed? 

Can you make a screen of what you are trying to do?

As stated, more information will be nice.  In Dolphin, most layout is controlled through the template engine.  There are html files with special code (keys) used to render content.  It is in these html template files (they are not true html documents so don't confuse them with html documents) you can make changes for the layout.
