Answer 1

这是该makecell软件包的一个可能的解决方案，它允许在标准列的单元格中进行换行，并对列标题进行通用格式设置：

    \documentclass[twoside]{article}
    \usepackage{multicol, booktabs}
    \usepackage{makecell}
    \renewcommand{\theadfont}{\small\bfseries}
    \setlength{\tabcolsep}{4pt}

    \begin{document}

    \begin{multicols}{2}
      \begin{table*}[t]
    \caption{Comparison with other state of art detection tools}
    \label{tab:example}
    \small
    \centering
    \begin{tabular}{lcccccc}
    \toprule\toprule
    \thead{Detection\\ Techniques} & \textbf{Algorithm} & \thead{Detection\\ Time} & \thead{RAM \\%
    Usage} & \thead{CPU\\ usage} & \thead{Database\\ Creation time} \\
    \midrule\midrule
    \\
    NAYATDROID & DRG-122 & Item 3 & Item 4 & Item 4 & Item 4\\ \\
    DroidSG & FNV Hash & Item 3 & Item 4 & Item 4 & Item 4\\ \\
    PTVDT& \makecell{GHU Hash,\\ FNV hash,\\ Nim hash} & Item 3 & Item 4 & Item 4 & Item 4\\ \\
    BGHFT& FVB Hash & Item 3 & Item 4 & Item 4 & Item 4\\ \\
    VFFG & \makecell{CDC Hash,\\ FNV hash} & Item 3 & Item 4 & Item 4 & Item 4\\ \\
    VBGFD & GBR Hash & Item 3 & Item 4 & Item 4 & Item 4\\
    \bottomrule \bottomrule
    \end{tabular}
    \end{table*}
    \end{multicols}
