Tabela tabularx longa -3 erros diferentes ao compilar no TeXstudio

Em um documento longo, tenho várias tabelas espalhadas por mais de uma página. A maioria deles contém muito texto, então estou usando tabularxpackage para ter a distribuição correta das larguras das colunas. Fiz isso seguindo o conselho de alguma outra pergunta daqui (não consigo encontrar agora) usando ltablexo pacote e tenho o seguinte documento. (exemplo)

Agora, até recentemente, tenho trabalhado principalmente com o ShareLaTeX, que foi capaz de compilar o documento e me mostrar os resultados.

Porém agora estou mudando para o TeXstudio, e ao tentar compilar a tabela lá, o log exibe os erros mostrados abaixo. Voltando ao ShareLaTeX, descobri que ele também mostra os mesmos erros, mas é capaz de exibir o resultado, e o resultado é satisfatório.

    ! LaTeX Error: Something's wrong--perhaps a missing \item.

    See the LaTeX manual or LaTeX Companion for explanation.
    Type  H <return>  for immediate help.
     ...                                              

    l.101 \end{tabularx}

    Try typing  <return>  to proceed.
    If that doesn't work, type  X <return>  to quit.



    ! Misplaced \noalign.
    \rowcolor ->\noalign 
                         {\ifnum 0=`}\fi \global \let \CT@do@color \CT@@do@color...
    l.101 \end{tabularx}

    I expect to see \noalign only after the \cr of
    an alignment. Proceed, and I'll ignore this case.

    ! LaTeX Error: There's no line here to end.

    See the LaTeX manual or LaTeX Companion for explanation.
    Type  H <return>  for immediate help.
     ...                                              

    l.101 \end{tabularx}

    Your command was ignored.
    Type  I <command> <return>  to replace it with another command,
    or  <return>  to continue without it.

Esses erros são repetidos diversas vezes; Copiei apenas parte do log sem que eles se repetissem. Tenho pelo menos quatro outras tabelas como esta e os mesmos tipos de erros aparecem em cada uma delas.

Sou bastante novo no TeX em geral, usando-o apenas para documentos universitários, então pode haver algo estupidamente errado com ele, mas não consigo identificar nada em particular.

Desde já, obrigado!

O problema é como quando você tem \captionum ambiente não flutuante ( tabularx), embora ltablexdefina tabularxser longtableo que define \caption.

Use \captionof{table}{...}fora tabularxpara obter o que deseja.

O principal erro, eu acho, é a forma como os comprimentos relativos são definidos para as Xcolunas. A soma dos coeficientes não deve ser igual a 1, mas sim ao número de colunas, 5, na sua versão.

Melhorei sua tabela usando o Stipo de coluna from siunitx, para ter um alinhamento no ponto decimal, e usei o \theadcomando from makecellpara ter uma formatação comum dos cabeçalhos das colunas e quebras de linha dentro desses cabeçalhos.

Acho que posso ter encontrado o motivo do erro, mas não estou 100% convencido disso.

Considere o MWE (versão abreviada do código problemático do OP):

\documentclass{report}
\usepackage{tabularx}    
\usepackage[labelfont=bf,textfont=normal,justification=justified,singlelinecheck=false]{caption}    
\usepackage{ltablex}

\begin{document}
    \begin{tabularx}{\textwidth}{
            >{\setlength\hsize{0.5  \hsize}\centering}X
            >{\setlength\hsize{0.15  \hsize}\centering}X
            >{\setlength\hsize{0.17 \hsize}\centering}X
            >{\setlength\hsize{0.08 \hsize}\centering}X
            >{\setlength\hsize{0.1 \hsize}\centering}X}  
%           \caption{\small Sample caption.\label{tab:qfd}} \tabularnewline
        A & B  & C  & D & E   \tabularnewline
        \hline
        1 & 2 & 3 & 4 & 5     \tabularnewline
    \end{tabularx}
\end{document}

1) Ele compila bem quando \captioné comentado, mas dá um erro sobre ...missing \itemquando \captioné deixado, semelhante ao que o OP relata.

2) Deixando \captiono comentário e alterando um deles \tabularnewlinepara \\, também teremos erro.

o que me leva a pensar que pode ter algo a ver com \\vs. \tabularnewlineAgora, a solução típica para isso é incluir \arraybackslashno arraypacote que basicamente tem a definição:

\def\arraybackslash{\let\\\tabularnewline}

Se incluirmos \arraybackslash(e uma ligeira modificação para \newcolumntypetornar as coisas mais compactas):

\documentclass{report}
\usepackage{tabularx}    
\usepackage[labelfont=bf,textfont=normal,justification=justified,singlelinecheck=false]{caption}    
\usepackage{ltablex}

\newcolumntype{Y}[1]{>{\setlength\hsize{#1\hsize}\centering\arraybackslash}X}
\begin{document}
    \begin{tabularx}{\textwidth}{Y{0.5}Y{0.15}Y{0.17}Y{0.08}Y{0.1}}  
            \caption{\small Sample caption.\label{tab:qfd}} \tabularnewline
        A & B  & C  & D & E   \tabularnewline
        \hline
        1 & 2 & 3 & 4 & 5     \tabularnewline
    \end{tabularx}
\end{document}

Agora funciona com a legenda incluída no tabularxambiente, sem erros.

Agora, não tenho certezapor queé assim, então, se surgir uma resposta mais completa, excluirei minha resposta. Por enquanto, fornecerei a solução rápida para @Slovakov:
