Multi-column RMarkdown pdf with tables: "! Package longtable Error: longtable not in 1-column mode."

Question

当RMarkdown文件包含Markdown表格时，是否可以将.rmd编织成多列.pdf？我正在尝试制作一个非常紧凑（小字体、最小间距等）的 pdf 以使用公式 sheet，但我无法将 .rmd 打印成包含多列的 pdf降价表。有解决此错误的方法吗？

Answer 1

你可以用我的 huxtable 包来做到这一点：

---
title: ""
output:
  pdf_document
classoption:
- twocolumn
---

Two-column text goes here...

```{r, echo = FALSE}
library(huxtable)
ht <- tribble_hux(
  ~Model, ~Formula,
  "Intercept only", "$\operatorname{Y_{i}} = \beta_{0} + \epsilon_{i}$"
)

# to allow printing maths in column 2:
escape_contents(ht)[, 2] <- FALSE

ht

```

More two-column text goes here...

您可能还对 position(h) <- "wrapleft" 以及 font_size 和 width 等其他房产感兴趣。

Answer 2

您的 table 中似乎没有任何 r 特定代码。除了降价 table，您可以简单地添加适当的乳胶表格：
