Make table fit into the column

Question

My table is so big that it doesn't fit into the column, is there a way to make it thinner and make it fit into the column?

Answer 1

For your table the easiest way seems to change the intercolumn space, e.g. by \setlength{\tabcolsep}{4.1pt}

Answer 3

How about you write the columns as rows and rows as columns. Like this:

\documentclass[10pt,conference]{IEEEtran} 
\IEEEoverridecommandlockouts

\usepackage{cite}
\usepackage{amsmath,amssymb,amsfonts}
\usepackage{algorithmic}
\usepackage{algorithm}
\usepackage{graphicx}
\usepackage{changepage}
\usepackage{lipsum}
\usepackage{ctable}% http://ctan.org/pkg/ctable
\usepackage{color, colortbl}

\begin{document}

\lipsum[2]

\begin{table}[htbp]
\centering
\caption{Quantifying the requirement-to-method Input Gold Standard}
\label{GoldStandardInputCompleteness}
    \begin{tabular}{|c|c|c|c|c|}
        \hline   
        \textbf{App}                    & \textbf{Chess}    & \textbf{Gantt}    & \textbf{iTrust}   & \textbf{JHot.}\\\hline
        \textbf{T\textsubscript{m}(\#)} & 563               & 1429              & 307               & 936           \\\hline
        \textbf{N\textsubscript{m}(\#)} & 2389              & 26842             & 7173              & 13382         \\\hline
        \textbf{E\textsubscript{m}(\#)} & 3064              & 61963             & 159358            & 122602        \\\hline
        \textbf{T\textsubscript{m}(\%)} & 9.36              & 1.58              & 0.18              & 0.68          \\\hline
        \textbf{N\textsubscript{m}(\%)} & 39.71             & 24.75             & 4.30              & 9.77          \\\hline
        \textbf{E\textsubscript{m}(\%)} & 50.93             & 68.67             & 95.52             & 89.54         \\\hline
        \textbf{Total}                  & 6016              & 90234             & 166838            & 136920        \\\hline
    \end{tabular}
\end{table}

i would make this table in the same way as your big table in {previous question):

\renewcommand\theadgape{}
\usepackage{siunitx}
\usepackage{etoolbox}

\usepackage{lipsum}
\begin{document}
\lipsum[66]
\begin{table}[htb]
