为什么第 1 列有额外的空间？

Question

我想要一个非常简单的表格，左列中有一个段落，右列中有一个图像，图像下方有一个标签。出于某种奇怪的原因，LaTeX 在段落前放置了一堆空白，我不知道为什么：

\noindent\begin{tabular}{|p{4in} p{1in}|}
\hline
Note: The strange word which occurs three times on the form above (including alone on the far right column) has been explained to me by a French speaker as the Latin word "idem" meaning "the same" or as we would say colloquially in English, ``ditto.''& \includegraphics[width=1in]{img/ch06-Ditto.png} ``ditto''\\
\hline
\end{tabular}

结果如下：

有人知道为什么左栏顶部似乎添加了一个额外的空白行吗？

Answer 1

这是因为图像被设置在第一行的基线，这使得它（垂直）突出于该行之上。

为了避免这种情况，请将图像“提升”到位：

\documentclass{article}

\usepackage{graphicx}

\begin{document}

\noindent\begin{tabular}{ | p{4in} p{1in} | }
  \hline
  Note: The strange word which occurs three times on the form above (including alone on 
  the far right column) has been explained to me by a French speaker as the Latin 
  word ``idem'' meaning ``the same'' or as we would say colloquially in English, ``ditto.''
  & {\centering\begin{tabular}[t]{ @{} c @{} }
    \raisebox{\dimexpr-\height+.6\normalbaselineskip}{\includegraphics[width=0.5in]{example-image}} \\ 
    ``ditto''
  \end{tabular}\par} \\
  \hline
\end{tabular}

\end{document}

请注意，我已将右侧列设置在它自己的 内tabular。这样，您可以自由地按自己想要的方式换行，而不是强制将换行符作为图像的标签。

Answer 2

无需猜测：

\documentclass{article}
\usepackage{graphicx}

\begin{document}

\noindent
\begin{tabular}{|p{4in} p{1in}|}
\hline
Note: The strange word which occurs three times on the form above 
(including alone on the far right column) has been explained to me 
by a French speaker as the Latin word ``idem'' meaning ``the same''
or as we would say colloquially in English, ``ditto.''
& \centering
\vspace{-\ht\strutbox}\includegraphics[width=1in,height=0.4in]{example-image} ``ditto''
\tabularnewline
\hline
\end{tabular}

\end{document}

这\vspace将设置第二列中（顶部对齐） parbox 的基线，但我们需要通过 LaTeX 自动添加的支柱高度进行备份。

在代码中我添加了height模拟您的图片；当然您必须将其删除。
