I have a large document with > 100 tables in the appendix and many references at various points in the document.

Is there a way to create a list of references in the sense of finding all ref{...}s to tables and figures in the text.

Example:
Consider the folling document with two pages of text and a section where all the referenced tables are listed.

documentclass{article}

begin{document}

section{text}

blabla ref{fo} blabla ref{fi} blabla ref{th}

clearpage

blabla ref{on} blabla ref{tw}

section{tables}

begin{table}caption{on}label{on}end{table}

begin{table}caption{tw}label{tw}end{table}

begin{table}caption{th}label{th}end{table}

begin{table}caption{fo}label{fo}end{table}

begin{table}caption{fi}label{fi}end{table}

end{document}

Now I'd like to have something like listofreferences telling me that tables 4 5 and 3 were referenced on page 1 and tables 1 and 2 were referenced on page 2

Something like this?

The code redefines ref and grabs the label name, puts it in a seq list and and grabs the page number of the current position where it appears, storing in a sequence as well. Those lists are then stored to the .lor file which is retrieved with listofreferences.

The macro trackonlylabeltypes stores the label types that should be tracked, e.g. figure or table, all others are ignored, unless nottrackallfalse is used.

Please note that the code may fail since crtrefcounter tries to determine the underlying counter using some heuristics. If unsure, use nottrackallfalse.

I modified Christan Hupfer's answer to also work with cleveref references and multiple ref's, e.g. Cref{table1,table2}. I'm posting this as a separate answer, but it's 99% based on Christian's solution:
