我有一个不适合幻灯片的 tikz 树。主题和行距已给出，所以我只想更改 tikz 节点中文本的行距。但对我来说没什么用 :(

答案1

插入 环境\linespread{1}\selectfont 中第一个节点定义之上tikzpicture。

答案2

由于columns环境仅包含树木，您可能希望将参数设置\linespread为1仅针对columns环境。

此外，该forest软件包使得绘制语言树变得更加容易。

这是修改后的版本Kevin C 的回答展示如何使用样式来减少排版树所需的代码并确保一致性。这是否有用可能取决于您要制作多少这样的树！

.wrap value用于自动将语言类别添加到节点。因此，Microsoft\\Noun\\ORG\\Arg2您可以写而不是Microsoft, noun org arg2。如果您需要经常使用它，您可能希望将样式名称缩写一点，以便您可以写Microsoft, noa2或任何其他名称。但是使用较长的名称更容易理解代码，并且最好选择您自己的缩写，以便它们对您有意义。

\beamertemplatenavigationsymbolsempty
\usepackage[utf8]{inputenc}
\usepackage[light]{iwona}

\forestset{
  noun/.style={
    content/.wrap value={##1\\Noun\\--\\--},
  },
  noun per/.style={
    content/.wrap value={##1\\Noun\\PER\\--},

  noun per arg1/.style={
