Is there a way to create a new table beneath the detail's section? I've seen it done but I can't figure out how to do it.

I think you'd have to have a code for the whole thing rather than just one section.
Like you'd have to remove it, have a code for the whole "Details" table, and add an extra section in.

I figured out how to make a new table and it appears above details and beneath interests, but the problem is the table border around extended network and blog space disappears. Also, I can't figure out how to delete the details section without ruining the code I used to make the new table.

This is the code I used. I put it in the bottom of heroes.
