使用 kable 或 kableExtra 左对齐表格标题

Question

是否可以左对齐表格标题？ 我对 APA6th 规则感到恼火，但我必须以某种方式左对齐表格标题。

以这张表为例：

library(knitr)
library(kableExtra) 

kable(mtcars[1:10, 1:6], format = "latex", caption = "I need this left-aligned.", booktabs = T) %>% 
      kable_styling(position = "left") %>%
      group_rows("Group 1", 4, 7) %>%
      group_rows("Group 2", 8, 10)

标题将始终位于表格上方的中心，即使我将表格 position 与kable_styling(position = "left")左对齐。

编辑：请参阅此处了解至少对我有用的临时解决方案。

You only need to add the Latex package caption in the YAML header section with singlelinecheck singlelinecheck=false specified to have the caption of your title left-aligned. 这是一个可重现的示例：

---
output:
  pdf_document: default
header-includes:
   - \usepackage[singlelinecheck=false]{caption}
---
```{r, echo = FALSE, message = FALSE}
library(knitr)
library(dplyr)
library(kableExtra)
```

```{r, echo = FALSE, message = FALSE}
kable(mtcars[1:10, 1:6], format = "latex", caption = "I need this left-aligned.", booktabs = T) %>% 
  kable_styling(position = "left") %>%
  group_rows("Group 1", 4, 7) %>%
  group_rows("Group 2", 8, 10)
```

Output：
