I have a problem using longtable, i used it because i needed a table that occupies two pages, and the caption that marks Table 4.1: Table of statistics, i want it to be for example Chart 4.1 : Table of Statistics, or something like that, i just need to use renewcommand i think, i have used it in figures and changed Figure to another thing, but I'm not being able to do so with longtable.... Any ideas? Thanks

\renewcommand\tablename{Chart}
\caption{Tabla de actividades}
\end{longtable}

Throws this error

! Misplaced \noalign. \caption ->\noalign \bgroup \@ifnextchar [{\egroup \LT@c@ption \@firstofone ... l.381 \caption {Tabla de actividades} ?

\begin{longtable}{|c|c|c|c|}

\caption{Tabla de Actividades}

If I try to put caption at the top, same as renew, it throws me some errors

! Extra alignment tab has been changed to \cr. \endtemplate

  • \renewcommand\tablename{Chart} will change the display, if you want separately counted tables and charts it's a bit trickier and you should clarify exactly what you do want. Commented Mar 22, 2015 at 19:19
  • It didn't work, throwed the error aboce Commented Mar 22, 2015 at 20:04
  • You put the definition in the wrong place, I'll post an answer Commented Mar 22, 2015 at 21:03
  • \caption is a table row you need \\ after it if it isn't the last row, (see the example in my answer) that is unrelated to the question about \tablename, please don't edit questions to ask unrelated questions as it makes the answers very hard for later readers to follow Commented Mar 22, 2015 at 21:32

As far as possible longtable uses the same caption settings as table so you just need to redefine \tablename

\documentclass{article}
\usepackage{longtable}
\begin{document}



\renewcommand\tablename{Chart} 
\begin{longtable}{cc}
\caption{zzz}\\
zz&zz\\
z&z
\end{longtable}

\end{document}

\caption in longtable is really a \multicolumn so like \multicolumn has to be the first thing in its cell, which is why you got an error if the redefinition is immediately before the caption.

  • Thanks, but I'm not getting it right :/ I'll post a larger version of the code right as it is... some parts are in spanish cuz i speak spanish. What I want is to change the Table 4.1, but it throws me errors Commented Mar 22, 2015 at 21:26
