# Resizing table when using package {threeparttable}

I'm using the {threeparttable} package because I want to use table notes, but I'm having a problem resizing my tables. If I use {adjustbox} to enclose {tabular} (or {tabularx}), I get an error message:

! You can't use \hrule' here except with leaders. \caption@hrule
->\hrule
\@height \z@  l.23 \end{tabular}}


The same applies if I use \resizebox or \scalebox at the same point in the code.

If I use {adjustbox} and enclose {threeparttable}, the code runs, but the fontsize of the caption and table note are also scaled down...

... which is not what I want!

Does anyone know a way to resize the table font only when using package {threeparttable}?

threeparttable wants to see tabular and tablenotes at the outer level, not buried into adjustbox.

Thinks very carefully before deciding to scale a table. For instance, a body text of 14pt is humongous and will make the scaled table disappear with respect to the text.

I reduced to 11pt, which is a quite large font size.
