为什么表格文本的垂直对齐不一致以及如何修复它？

Question

以下代码为第二行和第三行的单元格生成不同的垂直对齐方式（顶部对齐与居中）。顶部对齐是所需的结果。为什么会发生这种情况？我该如何修复？

\documentclass[11pt, letterpaper]{article}

\begin{document}
    
\begin{tabular}{|l|l|l|l|}
    \hline
    1 & 2 & 3 & 4 \\ \hline
    \textbf{Field 1} & \multicolumn{3}{p{10cm}|}{The label for Field 1 is aligned to the top of its cell, even though it is more than one line high due to this cell extending to multiple lines.} \\ \hline
    \textbf{Field 2} & Data for field 2 & \textbf{Field 3} & \begin{tabular}{@{}l@{}} List of \\ Items for \\ Third field \end{tabular} \\ \hline
\end{tabular}
    
\end{document}

Answer 1

这个怎么样？

\documentclass{article}
\begin{document}
\begin{tabular}{|l|l|l|l|}
    \hline
    1 & 2 & 3 & 4\\
    \hline
    \textbf{Field 1}&
    
    \multicolumn{3}{p{10cm}|}{The label for Field 1 is aligned to the
      top of its cell, even though it is more than one line high due
      to this cell extending to multiple lines.}\\

    \hline

    \textbf{Field 2}&Data for field 2&\textbf{Field 3}&
    \begin{tabular}[t]{@{}l@{}} List of\\
      Items for\\
      Third field
    \end{tabular}
    \\
    \hline
\end{tabular}
\end{document}

Answer 2

这是你想要的吗？我用包简化了你的代码makecell，并m在以下位置使用了列类型p：

\documentclass[11pt, letterpaper]{article}
\usepackage{array}
\usepackage{makecell}

\begin{document}

\setlength{\extrarowheight}{3pt}
\begin{tabular}{|l|l|l|l|}
    \hline
    1 & 2 & 3 & 4 \\ \hline
    \textbf{Field 1} & \multicolumn{3}{m{10cm}|}{The label for Field 1 is aligned to the top of its cell, even though it is more than one line high due to this cell extending to multiple lines.} \\ \hline
    \textbf{Field 2} & Data for field 2 & \textbf{Field 3} & \makecell[l]{List of \\ Items for \\ Third field } \\ \hline
\end{tabular}

\end{document}
