I use threeparttablex to provide longtables with the threeparttable functionality. That works well in general.

However, I need to load floatrow as follows:

\usepackage{floatrow}
\DeclareFloatFont{small}{\small}% "scriptsize" is defined by floatrow, "tiny" not
\floatsetup[table]{font=small, capposition=top}

Unfortunately, now the threeparttablex tables are not centered anymore.

Does anyone have a solution for this problem?


Here is a MWE:

Here's a minimal example which demonstrates that the problem is caused by the combination of floatrow and longtable.

\documentclass{article}
\usepackage{longtable,showframe}
\usepackage{floatrow}

\begin{document}

\begin{longtable}{lccc}
  \caption{Caption which must extend to quite a long thing if we're going to see the problem clearly.} \\
  competence 1 & \textbf{0.75} & -0.14 & 0.04 \\
  competence 2 & \textbf{0.84} & -0.06 & -0.07 \\
\end{longtable}

\end{document}

problem

The floatrow documentation mentions the fact that longtable has been modified to work with floatrow. What it fails to make clear is that this is not something longtable does, but something floatrow does.

In floatrow.sty, we find

\AtBeginDocument{%
\@ifundefined{LT@array}{\@tempswafalse}{\@tempswatrue}
\if@tempswa\RequirePackage{fr-longtable}\fi}

So, floatrow is loading fr-longtable.sty if longtable has been loaded before the document begins.

It is possible - although I can't confirm this - that the patch worked OK with the version of longtable available at the time.

\ProvidesPackage{floatrow}
       [2008/08/02 v0.3b floatrow: float package extension]

shows floatrow to have last been updated in 2008, while

\ProvidesPackage{fr-longtable}
       [2007/11/28 v0.1b (beta) floatrow: additions for longtable]

shows the longtable patch to be from 2007. In contrast,

\ProvidesPackage{longtable}
          [2014/10/28 v4.11 Multi-page Table package (DPC)]

tells us that longtable was last updated in 2014.

So one possibility is that the patch worked in 2007 but does not work now.

The most straightforward way to workaround this particular issue, at least, is to explicitly tell longtable that it should be centred

\begin{longtable}[c]{lccc}

centred <code>longtable</code>

However, this will not work if you wanted the table to be set left or right as the caption is misplaced in those cases. That is

\begin{longtable}[l]{lccc}
...

\begin{longtable}[c]{lccc}
...

\begin{longtable}[l]{lccc}

produces

left, centre and right - but not quite

So the problem is obviously somewhat deeper than a simple failure to specify a default alignment when redefining the longtable environment.

Indeed, it is not even the patch itself which is the problem. Blocking the loading of the patch does not resolve the issue. In fact, not loading floatrow doesn't resolve it either. It appears to be a longtable issue which can be reproduced even without floatrow, as noted by David in chat ... [That is, this has been reported to the author of longtable...]

The only reason loading floatrow appears to cause it is that floatrow fails to make centring the default, which longtable itself does.

\documentclass{article}
\usepackage{longtable,showframe}
\usepackage{floatrow}

\begin{document}

\begin{longtable}[l]{lccc}
  \caption{Caption which must extend to quite a long thing if we're going to see the problem clearly.} \\
  competence 1 & \textbf{0.75} & -0.14 & 0.04 \\
  competence 2 & \textbf{0.84} & -0.06 & -0.07 \\
\end{longtable}
\begin{longtable}[c]{lccc}
  \caption{Caption which must extend to quite a long thing if we're going to see the problem clearly.} \\
  competence 1 & \textbf{0.75} & -0.14 & 0.04 \\
  competence 2 & \textbf{0.84} & -0.06 & -0.07 \\
\end{longtable}
\begin{longtable}[r]{lccc}
  \caption{Caption which must extend to quite a long thing if we're going to see the problem clearly.} \\
  competence 1 & \textbf{0.75} & -0.14 & 0.04 \\
  competence 2 & \textbf{0.84} & -0.06 & -0.07 \\
\end{longtable}
