For other readers, I summarize your specification.
Heading in centered with two lines: first line contains “Chapter 1”, second line “Introduction” with a large vertical spacing between both lines
Corresponding entry should be “Chapter 1 Introduction” on a single line
You must remember that entries in TOC are simply a copy of the heading paragraphs. This means that semantically a heading, whether written on several lines or not, must be made of a single paragraph. Unfortunately as you didn’t enable View
>Formatting Marks
I have no idea on how you vertically spaced your heading.
Here is how it must be handled. Your heading is entered as:
Chapter 1Shift
+Enter
IntroductionEnter
Shift
+Enter
is a line break. It does not create a paragraph break as does Enter
. Consequently everything typed is a single paragraph.
Assign style Heading 1 to this paragraph. Customize it to fit your needs, e.g. uppercase or small caps and center-aligned. To space the line, tune Line Spacing in Indents & Spacing
. I hope for you you’ll never need 3 lines or the result will be awfully ugly. In this case another trick is possible provided you know what a character style is.
In the TOC, a line break turns into a space. So, everything is on a single line. You can tune the appearance of the entry customizing Contents 1.
EDIT
In case “Chapter 1” is provided by Tools
>Chapter Numbering
(again, I can’t tell from the screenshot because View
>Field Shadings
was no enabled), the line break can be added automatically. In the Position
tab, you can set Number followed by New Line
.
I remind you that "Chapter " (with a space) can be added automatically by defining as Separator Before in Numbering
tab.
