# Subtables and lineno incompatibility

Is there any incompatibility between packages subcaption and lineno?

I cannot compile this (dummy) text:

\documentclass{revtex4-1}

\usepackage{subcaption}

\usepackage[mathlines]{lineno}% Enable numbering of text and display math
\modulolinenumbers[2]% Line numbers with a gap of 5 lines
\linenumbers\relax % Commence numbering lines

\begin{document}

I get this kind of errors:

! Improper \prevdepth. \prevdepth l.16 ...n{\label{tab:Taula} Mean uncertainties...} You can refer to \spacefactor only in horizontal mode; you can refer to \prevdepth only in vertical mode; and neither of these is meaningful inside \write. So I'm forgetting what you said and using zero instead. ! You can't use \prevdepth' in restricted horizontal mode. \nointerlineskip ->\prevdepth -\@m \p@ l.16 ...n{\label{tab:Taula} Mean uncertainties...} Sorry, but I'm not programmed to handle this case; I'll just pretend that you didn't ask for it. If you're in the wrong mode, you might be able to return to the right one by typingI}' or I$' orI\par'. ! Missing$ inserted.

UPDATE: It looks like the incompatibility appears when using the revtex documentclass.

• \linenumbers\relax ? If I comment that out, the compilation goes normally The package is about 9 years old. Is it designed for usage with tables at all? – user31729 Aug 22 '14 at 10:32
• @ChristianHupfer Yes, but without line numbering. Is there any alternative to lineno? – Medical physicist Aug 22 '14 at 10:35
• caption should not be used with revtex; the subfig package is compatible, loading it with \usepackage[caption=false]{subfig}. – egreg Aug 22 '14 at 10:52
• @egreg Using subfig I get the same error: ! Improper \prevdepth... – Medical physicist Aug 22 '14 at 11:07

Ok, I found an easy solution:

Remove the lineno package and add the option linenumbers in documentclass:

\documentclass[linenumbers]{revtex4-1}

\usepackage{subcaption}

%\usepackage[mathlines]{lineno}% Enable numbering of text and display math
%\modulolinenumbers[2]% Line numbers with a gap of 5 lines
%\linenumbers\relax % Commence numbering lines

• In as much is this the solution? ;-) – user31729 Aug 22 '14 at 11:35
