longtable 中沒有圖片邊框

Question

\begin{longtable}{|lllllllll|} 
        %   [ht] 
        \caption{Create } \\ 
        %\label{step 3}
        \hline
        \multicolumn{3}{|l|}{\textbf{Prefix}} & \multicolumn{2}{l|}{\textbf{Class label}} & \multicolumn{2}{l|}{\textbf{Intersection}}\\
        \hline
        \endfirsthead
        \multicolumn{6}{c}%
        {\tablename\ \thetable\ -- \textit{Continued from previous page}} \\
        \hline
        \multicolumn{3}{|l|}{\textbf{Prefix}} & \multicolumn{2}{l|}{\textbf{Class label}} & \multicolumn{2}{l|}{\textbf{Intersection}}\\
        \hline
        \endhead
        \hline \multicolumn{6}{r}{\textit{Continued on next page}} \\
        \endfoot
        \hline
        \endlastfoot
        %   \begin{tabular} {lllllll}[ht]\\ 


        %   \hline \multicolumn{3}{|l|}{\textbf{Prefix}} & \multicolumn{2}{l|}{\textbf{Class label}} & \multicolumn{2}{l|}{\textbf{Intersection}} \\ \hline 

        \multicolumn{7}{|l|}{\textbf{Begin}}\\ \hline

        \multicolumn{7}{|l|}{\textbf{Initial}}\\ \hline

        \parbox[|c|]{2cm}{
    \includegraphics[scale=0.40,height=8 cm,width=10 cm]{initialfgist.jpg}} \\ \hline
        \end{longtable}

圖片的右側和上邊框沒來。請告訴我我做錯了什麼？

Answer 1

\parbox[|c|]{2cm}{
    \includegraphics[scale=0.40,height=8 cm,width=10 cm]

這指定了 2 厘米寬的盒子中的 10 厘米寬的圖像，因此預計會出現疊印。至少它會指定如果它是\parbox{2cm}但是 \parbox[|c|]語法錯誤（儘管 Latex 不會這樣報告），則可選參數只能是c,t或b。

您只想指定一的scale，width並且您根本height不想要。\parbox

Answer 2

該cellspace套件是為此而設計的：它在列中定義了單元格頂部和底部的最小垂直間距，並帶有以字母為前綴的說明符S（或C如果您使用siunitx）。我還簡化了您的程式碼並糾正了錯誤的地方：

\documentclass{article}
\usepackage[showframe]{geometry}
\usepackage{graphicx}
\usepackage{array, longtable}
\usepackage{cellspace}
\setlength\cellspacetoplimit{3pt}
\setlength\cellspacebottomlimit{3pt}

\begin{longtable}{|*{7}{Sl}|}
    \caption{Create } \\
    %\label{step 3}
    \hline
    \multicolumn{3}{|Sl|}{\textbf{Prefix}} & \multicolumn{2}{l|}{\textbf{Class label}} & \multicolumn{2}{l|}{\textbf{Intersection}}\\
    \hline
    \endfirsthead
    \multicolumn{6}{Sc}%
    {\tablename\ \thetable\ -- \textit{Continued from previous page}} \\
    \hline
    \multicolumn{3}{|Sl|}{\textbf{Prefix}} & \multicolumn{2}{l|}{\textbf{Class label}} & \multicolumn{2}{l|}{\textbf{Intersection}}\\
    \hline
    \endhead
    \hline \multicolumn{7}{Sr}{\textit{Continued on next page}} \\
    \endfoot
    \hline
    \multicolumn{7}{|Sl|}{\textbf{Begin}}\\ 
    \hline
    \multicolumn{7}{|Sl|}{\textbf{Initial}}\\ 
    \hline
    \includegraphics[scale=0.40]{initialfgist.jpg} & & & & & & \\
    \hline
    \end{longtable}
