Thin Line under Heading - Border Line?

users
#1

I'm trying to recreate that thin grey line which appears below a title
heading on Wikipedia pages.

ex. https://en.wikipedia.org/wiki/Book

Is that considered a Border Line in Libre Writer?

If so, I tried to create one following these steps
https://help.libreoffice.org/Common/Defining_Borders_for_Tables_and_Table_Cells

But, after I highlight my heading and the click Table, the Properties under
that is all grayed out.

Thank you.

You are working with the wrong style. You need to change the style for the title heading. This style should have several Tabs which include Font Effects which is where you need. There look for the title underlining. The drop down list to its right contains the type of underlining, and the next drop down list contains the possible colors that can be used.

Why would you expect the formatting for a Header to be within a Table
properties?

Why didn't you select the header then styles/edit and then choose
an appropriate border? That appears to work as you wish.

The underlining only underlines the text itself. To 'underline' the
whole row, you need to set a border.
