Latex kable 并排桌 "Not in outer par mode"

Question

我正在尝试创建一个具有并排 table 的页面。我使用其他 SO 答案来做一个简单的 table

```{r start-block, include=F,echo=F}
library(dplyr)
library(knitr)
library(kableExtra)
```

```{r sample, echo=FALSE, results='asis'}
t1 <- kable(head(mtcars)[1:3], format = "latex", booktabs = TRUE) %>%  kable_styling(latex_options = c("striped"), font_size=5)
t2 <- kable(head(mtcars)[4:6], format = "latex", booktabs = TRUE) %>%  kable_styling(latex_options = c("striped"), font_size=5)
cat("\n")
cat("\newpage")
cat("\begin{table}[!htb]")
cat(c("\begin{minipage}{.5\linewidth}
       \caption{}
       \centering",
         t1,
     "\end{minipage}%
     \begin{minipage}{.5\linewidth}
       \centering
         \caption{}",
         t2,
     "\end{minipage}") )
cat("\end{table}")
```

我正在尝试使用自定义 table（.RDS 格式文件：tbl）重现相同的行为。这在没有并排 tables.

的情况下工作正常

```{r table, echo=FALSE, results='asis'}
tbl <- readRDS("table.RDS") #load file using the link "tbl"
cat(tbl)
```

byt 当我并排尝试此 table 时出现错误。

```{r table2, echo=FALSE, results='asis'}
cat("\n")
cat("\newpage")
cat("\begin{table}[!htb]")
cat(c("\begin{minipage}{.5\linewidth}
       \caption{}
       \centering",
         tbl,
     "\end{minipage}%
     \begin{minipage}{.5\linewidth}
       \centering
         \caption{}",
         tbl,
     "\end{minipage}") )
cat("\end{table}")
```

！ LaTeX 错误：不在外部标准模式中。

我建议使用 LaTeX 包 subcaption 来构建并排 tables/figures。

.Rmd 文件示例：

---
title: "Answer for SO Question 50879745"
header-includes:
  \usepackage{subcaption}
  \usepackage{booktabs}
  \usepackage[table]{xcolor}
---


```{r start-block}
library(dplyr)
library(knitr)
library(kableExtra)
opts_chunk$set(echo = FALSE)
``` 

Build two example tables based on the `mtcars` data set.


```{r sample, results='asis'}
t1 <- kable(head(mtcars)[1:3], format = "latex", booktabs = TRUE) %>%  kable_styling(latex_options = c("striped"), font_size=5)
t2 <- kable(head(mtcars)[4:6], format = "latex", booktabs = TRUE) %>%  kable_styling(latex_options = c("striped"), font_size=5) 
```

Modify the tables to use the `subtable` environment and added labels and
captions.

```{r}
t1 <- gsub("\begin{table}[H]", "\begin{subtable}[b]{0.48\linewidth}\n\caption{\label{tab:1a}This is Table 1 in the example, but now labeled with a (a).}\n", t1, fixed = TRUE)
t1 <- gsub("\end{table}", "\end{subtable}", t1, fixed = TRUE) 

t2 <- gsub("\begin{table}[H]", "\begin{subtable}[b]{0.48\linewidth}\n\caption{\label{tab:1b}Shorter caption.}", t2, fixed = TRUE)
t2 <- gsub("\end{table}", "\end{subtable}", t2, fixed = TRUE) 
```

Place the tables into the document.

```{r, results = "asis"}
cat("",
    "\begin{table}[!htb]",
    "\centering",
    "\caption{\label{tab:tab1}Two tables, side-by-side.}",
    t1,
    t2,
    "\end{table}",
    "",
    sep = "\n") 
```

Another example, start by reading in a rds file.


```{r table, results = "asis"}
tbl <- readRDS("table.RDS") #load file using the link "tbl"
cat(tbl)
```

A few modifications to Table~\ref{tab:comments-block} will be made so that we
can show the table twice in a `subtable`.

```{r table2_mod}
tbl <- gsub("\begin{table}", "\begin{subtable}[t]{0.48\linewidth}", tbl, fixed = TRUE)
tbl <- gsub("\end{table}", "\end{subtable}", tbl, fixed = TRUE) 
```

Printing the tables works, see \ref{tab:tab3}, but there is overlap as the
tables are too wide.  Consider the `tabularx` package as a solution or an ad hoc
approach of changing the font size.

```{r, results = "asis"}
cat("",
    "\begin{table}[!htb]",
    "\centering",
    "\caption{\label{tab:tab3}Two tables, side-by-side.}",
    # "\scriptsize",
    tbl,
    tbl,
    "\end{table}",
    # "\normalsize",
    "",
    sep = "\n") 
```
