Floating table for new page

Question

Hello,

I am trying to adjust a table so that it stays on the same page of the section that was created to compose it, however, as much as it is an empty page section with only this table, it automatically moves to a new page leaving the previous one blank.

\documentclass[a4paper,12pt,oneside,onecolumn,final,fleqn]{repUERJ}                           
\usepackage{graphicx}       
\usepackage{subfig}
\usepackage{multirow}
\usepackage{amsmath,amssymb}  
\usepackage[alf]{abntex2cite} 
\usepackage[font=default,frame=no]{repUERJformat}                                             
\usepackage[maxfloats=25]{morefloats}
\usepackage{array}
\setlength\extrarowheight{2pt}
\usepackage[section]{placeins}
\usepackage{placeins}`

My table:

\begin{table}[h] {12cm}
    \centering
    \caption{Variáveis e Fontes dos Dados}
    \label{Variáveis e Fontes dos Dados}
    \begin{tabular}{cc}
        \textbf{Variável}                                                                                                                                               & \textbf{Fonte} \\ \hline
        \multicolumn{1}{c|}{I  }                                                                                                             & SEV           \\ \hline
        \multicolumn{1}{c|}{P }                                                                                                                              & IBGE           \\ \hline
        \multicolumn{1}{c|}{A}                                                                                                                         & IBGE           \\ \hline
        \multicolumn{1}{c|}{\begin{tabular}[c]{@{}c@{}}T = Intensidade Energética\\ O\end{tabular}} & IBGE e BEN     \\ \hline
    \end{tabular}
\end{table}

I’ve tried too many variants of package options float, such as the [H], but it did not change that question.

NOTE: I am using the repUerj template available here

Answer 1

Try eliminating the second load of placeins in

\usepackage[section]{placeins}
\usepackage{placeins}

Maybe that erased the option section of the first call. If it doesn’t work, try to force before the section with ' Floatbarrier'

\begin{table}
....
\end{table}

Algum texto finalizando a seção.

\FloatBarrier

\section{próxima seção}

But I recommend using this kind of thing only at the end. Let the table and figures float in the drafts. Normally Latex finds a better position than I imagine. Only in very short texts do I need to force the position of the figure.

If none of this still works, you do not need to let the table float. Remove the tabular from within table and use \captionof.

\begin{minipage}{\textwidth}
  \centering
  \captionof{table}{Variáveis e Fontes dos Dados}
  \label{Variáveis e Fontes dos Dados}
  \begin{tabular}{cc}
    \multicolumn{1}{c|}{I} & SEV \\ \hline
    \multicolumn{1}{c|}{P} & IBGE \\ \hline
    \multicolumn{1}{c|}{A} & IBGE \\ \hline
    \multicolumn{1}{c|}{\begin{tabular}[c]{@{}c@{}}T = Intensidade Energética
                        \\ O\end{tabular}} & IBGE e BEN \\ \hline
    \end{tabular}
\end{minipage}
