I do not know how you reached it. The way I would do it would be to select two of the entries in the TOC for the same level and add an interior border. I think you meant the Borders control in the paragraph group of the Home tab.



This should modify the TOC1 style and do it for all entries of that level. It may also handle the lower levels if your TOCx styles cascade.

To add to what Charles has said, even if you are modifying a paragraph style, you will have to select two consecutive pararaphs so that you can access the interior horizontal border.

That makes sense now, many thanks.

Actually, it doesn't really make sense, but it is how it works. :-)

I was originally trying to adjust the borders via the 'References' menu, but that doesn't give u a 'middle' border option for some reason.

Not sure why one allows a 'middle' border and the other doesn't!
