自定义 tcolorbox 和表格环境中的奇怪垂直间距

自定义 tcolorbox 和表格环境中的奇怪垂直间距

我试图让灰色codebox与表格右侧的解释很好地对齐，但显然垂直对齐有点偏离，我不确定原因。

此外，如果解释跨越多行，问题似乎会更严重。理想情况下，我希望tcolorbox左侧的解释位于右侧解释的垂直中间。

奖金：我可以在宏中放入一些东西吗methodt，这样我就不必把\code{}每个条目都放在左边了？

这是一个可重现的示例，下面是一张图片：

我不确定为什么这些框没有对齐，但我会以不同的方式做这件事并使用sidebyside 彩色盒子. 如果你定义：

\newtcolorbox{CODE}{
    sidebyside,
    sidebyside align=top,
    colback=light-gray,
    colframe=white,
    bicolor,
    colbacklower=white,
    righthand width=2.5in
}
\newcommand\Code[2]{\begin{CODE}#1\tcblower#2\end{CODE}}

然后你可以用以下方法替换你的方法部分

    \begin{methodt}{Rectangles}
      \Code{rect(x, y, width, height)}{A rectangle whose top-left corner is at (x, y); Pen automatically moved}
      \Code{fillRect(x, y, width, height)}{A solid rectangle}
      \Code{strokeRect(x, y, width, height)}{An outline rectangle}
      \Code{clearRect(x, y, width, height)}{Clear a portion or all of a rectangle}
    \end{methodt}

（我已经tabular从methodt环境中移除了环境）以产生：

顺便说一句，我也会彩色包包，而不是颜色...尽管我无法指出这在何处会产生影响:)
