Centering 'Page' word over page numbers in table of content

Question

I want to make the word 'Page' centered over page numbers for the following Latex template in the following pages:

• table of contents
• table of figures
• table of tables

I tried this solution, but it's not reliable since I have 'Title/Table/Figure' words on the other side of the page.

The following is a screenshot of the current template ('page' word aligned right):

Answer 1

What do you mean by centered? In your example should Page be centered with respect to the page I, or the page II, or in the middle of II?

Here is some code for you, and others, to try.

\documentclass{book}
\usepackage{lipsum}
\begin{document}
\frontmatter
\pagenumbering{Roman}
\tableofcontents
\addtocontents{toc}{Title \protect\hfill \rlap{\hspace{-1.5em}Page}

\chapter{Dedication}
\lipsum
\chapter{Acknowledgement}
\mainmatter
\chapter{One}
\end{document}

The \addtocontents{file}{text} inserts text into file where file is normally one of toc, lof or lot for the table of contents and the list of... files.

The \rlap effectively makes its argument take zero space and then the `\hspace{-1.5em} moves the zero-spaced text left the given amount. This should be adjusted to your particular document design.

I found one problem with the above code in that an error (missing \item ?) was reported for the Dedication ToC entry. Just ignoring this everything looked well. Hopefully somebody will provide a solution to this.

I have now found a solution as below:

% tocpageprob.tex SE 505981
\documentclass{book}
\usepackage{lipsum}
\begin{document}
\frontmatter
\pagenumbering{Roman}
%\tableofcontents
\addtocontents{toc}{Title \protect\hfill \rlap{\hspace{-1.5em}Page}\par}
\tableofcontents

\chapter{Dedication}
\lipsum
\chapter{Acknowledgement}
\mainmatter
\chapter{One}
\end{document}

I messed up my original code for the \addtocontents{toc}{...}
