How to remove white space after table and before new section?

Question

Kindly please help me soon, I must submit my paper as soon as possible and still there is a problem and white space and though I used htp for table, my table come between the text! also, I've searched a lot and still have this problem, after a long table there is a white space that the section can be in that space. My LaTeX code is as below:

\documentclass{cta-author}
\usepackage{natbib}
\usepackage{longtable}
\usepackage{lineno,hyperref}
\usepackage{lineno}
\usepackage{parskip}
\usepackage[utf8]{inputenc}
\usepackage{framed} % Framing content
\usepackage{multicol} % Multiple columns environment

\usepackage{textcomp}
\usepackage[T1]{fontenc}
\usepackage{resizegather}
\usepackage{booktabs}
\usepackage{bm}
\usepackage[font=small,skip=0pt]{caption}
\usepackage{setspace}

\begin{document}
{text}
\subsection{text}
\begin{table}[!t]
\caption{text1}
\label{table1}
\centering
\resizebox{0.48\textwidth}{!}{%
    %{\small \begin{center}
    \begin{tabular}{|l|}
        %\begin{longtable}{l}
        %       \centering
        \toprule\toprule
{text}
        \bottomrule\bottomrule
        \end{tabular}
}
\end{table}
\begin{table}[h]
        \caption*{\raggedright Continuation of Table \ref{table1}:}
    \label{table2}
    \centering
    \resizebox{0.48\textwidth}{!}{%
        \begin{tabular}{|l|}
            \toprule\toprule
{text3}
        \end{tabular}}
    \vspace{-5pt}
    \end{table}
\section{Simulation Results}
\label{section 2}
{text}
\\
\raggedbottom
    \begin{table}[htp]
        \caption{Simulation}
        \label{Table4}
        \centering
    \begin{spacing}{1.5}
            \small\addtolength{\tabcolsep}{-15pt}
            \begin{tabular}{l c}
                \toprule\toprule
{text5}
                \bottomrule\bottomrule
            \end{tabular}
        \end{spacing}
    \vspace{-10mm}
    \end{table}
{text}
\end{document}

Answer 1

Removing \vfill should do the trick as Mico said.

Also, you might be interested in this question and its answer.

Here is the full (corrected) MWE assuming article document class.

\documentclass{article}

\usepackage{graphicx}
\usepackage{booktabs}

\begin{document}
\begin{table}[h]%[!htbp]%[tp]
\caption*{\raggedright Table 1}
\label{table3new}
\centering
\resizebox{0.48\textwidth}{!}{%
    \begin{tabular}{|l|}
        \toprule\toprule
            {text}\\
                \bottomrule\bottomrule
    \end{tabular}}
\vspace{-5pt}
\end{table}
%\vfill
\section{Simulation Results}    
\label{section Five}
{text}.\\
\raggedbottom

\begin{table}[h]%[!htbp]%[tp]
\caption*{\raggedright Table 2}
\label{table3new}
\centering
\resizebox{0.48\textwidth}{!}{%
    \begin{tabular}{|l|}
        \toprule\toprule
            {text}\\
                \bottomrule\bottomrule
    \end{tabular}}
\vspace{-5pt}
\end{table}

{text again}
\end{document}

Answer 2

Use \vspace*{-\baselineskip} after the image or table.

As to make it global (I.e., after each image or table), I do not know how except via using custom style.

E.g.,

\newenvironment{rLongtable}{
  \vspace*{-\baselineskip}
  \begin{longtable}
}
{
  \end{longtable}
  \vspace*{-1.7\baselineskip}
}
