将森林树木放入表格单元格中

Question

我想在表格第一列的每个单元格中放置一棵森林树。这样做时会出现一些问题：间距太小，表格其余部分的数字会移到底部。我对如何使用它了解不够多，无法forest弄清楚如何在它周围添加间距，我也不知道它如何与乳胶表交互。这是它现在的样子：

Answer 1

这是一个建议。

1. 将forests 包裹进去\vcenter{\hbox{...}}以使它们垂直居中。
2. forest基于 Ti钾Z，并且在方程中，即局部地，每个的边界框都会增加。与或tikzpicture等标准方法相比，这使我们能够获得更精细的填充控制。\renewcommand{\arraystretch}{...}\\[...]
