# You can't use \prevdepth' in restricted horizontal mode

I've had some troubles typesetting a table. At first, the table wasn't being centering despite my code. And then when I used the adjustbox command to resize the table Latex gave me the following error:

You can't use \prevdepth' in restricted horizontal mode.

Here is the code

\begin{table}[ht]
\centering
\begin{threeparttable}
\caption{Changes in Wage Inequality and Institutions}
\begin{tabular}{@{}lcccc@{}}
\toprule
& \multicolumn{1}{c}{1980--1990} & \multicolumn{1}{c}{1990--2000} & \multicolumn{1}{c}{2000--2010} & \multicolumn{1}{c}{2010--2015} \\ \midrule
Wage Inequality       &     $\underset{(6.0)}{12.4}$      &  $\underset{(7.3)}{8.7}$    & $\underset{(3.5)}{4.0}$     &    $\underset{(3.3)}{4.3}$       \\
Manufacturing         &        $\underset{(3.3)}{-4.0}$      & $\underset{(2.1)}{-2.8}$   &  $\underset{(2.0)}{-3.0}$  & $\underset{(0.8)}{-0.5}$    \\
Union Membership      &    $\underset{(5.0)}{-9.8}$  &  $\underset{(3.9)}{-2.3}$       & $\underset{(5.0)}{-0.01}$   & $\underset{(5.4)}{-0.8}$          \\
Managerial Employment &   $\underset{(22.2)}{34.5}$      & $\underset{(22.1)}{31.7}$   & $\underset{(25.6)}{23.9}$   & $\underset{(8.5)}{-0.5}$       \\ \bottomrule
\end{tabular}
\end{threeparttable}
\begin{tablenotes}

And the packages from my preamble

\usepackage{tabularx}
\usepackage{graphicx}
\usepackage{float}
\usepackage{fancyhdr}
\usepackage{afterpage}
\usepackage[left=2cm,top=2cm,right=2cm,bottom=3cm,bindingoffset=0.5cm]{geometry}
\usepackage{booktabs}
\usepackage[labelfont=bf]{caption}
\usepackage[flushleft]{threeparttable}
\usepackage{ragged2e}
\usepackage{color}
\usepackage{rotating}
\usepackage[bottom]{footmisc}
\usepackage[caption=false]{subfig}

• I didn't check the error about \prevdepth but if you want your table to be centered, just remove the flushleft option when you load the threeparttable package. – Eric Domenjoud Feb 4 at 17:51
• Welcome to TeX S.E. ! Please put your preamble and your table in one single MWE. Thanks! – sztruks Feb 4 at 18:25

The problem is simple: you can't have a threeparttable environment inside adjustbox.

Scaling a table should be the very last resort. In this case you don't even need threeparttable.

\documentclass{article}
\usepackage{amsmath}
\usepackage{booktabs}

\newcommand{\data}[2]{$\underset{(#1)}{#2}$}

\begin{table}[ht]

You could use threeparttable inside adjustbox, provided you add a minipage; but this is the output you get with your code after adding \begin{minipage}{\textwidth} before \begin{threeparttable} and \end{minipage} after \end{threeparttable}

You can notice the wrong space before the note text.
