IMHO, this is not a TOC but some kind of “meta-TOC” because it lists “Table of contents…iii” as part of the list and the “real TOC” seems to start after the “List of abbreviations…viii” (plural is preferable) without page break.

Such short “meta-TOC” should be created with cross-references. You can put it into an ordinary Writer table (without borders) to simplify formatting. Then it is easy to put column headings n the first row. Cross-references can capture text as well as page number or chapter number. Thus there is no difficulty to get what you want.

You can uncheck the checkbox Protected against manual changes in the options for Table of Contents, but I think the easiest way is not to use the Title in the Table of Contents and create own Title etc. Example is here example-rejstrik.odt
