Question

目标我一直想创建一个pdf报告功能，但是我无法按照自己的意愿重新设置pdf的样式。我要解决的问题之一是无法将表格向左对齐。现在它居中。

系统和其他

CentOS 6.9版（最终版）
TeX 3.141592（Web2C 7.5.6）

template.Rmd

---
title: "Reporting"
output: pdf_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
```{r, results='asis', echo=FALSE}
knitr::kable(head(cars), format = "markdown") %>%
  kable_styling(bootstrap_options = "striped", full_width = F, position = "left")
```

build_report.R

# Libraries
require(knitr)
require(markdown)
library(RMySQL)
library(png)
library(kableExtra)

# create .md file
knit("template.Rmd", "template.md")

# create .html file
markdownToHTML("template.md", "template.html", options=c("use_xhml"))

# create .pdf file
command <- paste0("pandoc -V geometry:'left=0.5in,bottom=1in,top=1.5in' -s ", "template.html", " -o ", "output.pdf")
system(command)

output.pdf 输出示例（忽略了无关信息）1

Answer 1

将format = "markdown"中的kable移到library(kableExtra)上

Answer 2

可以在@Hao的帮助下解决它

1）从.Rmd到.md直接转换为PDF，省略markdownToHTML（）

2）将库（kableExtra）包含在 template.Rmd 中，而不包含在 build_report.R

中

3）使用格式=“ markdown”

template.Rmd

---
title: "Reporting"
output: pdf_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
```{r, results='asis', echo=FALSE}
knitr::kable(head(cars), format = "markdown") %>%
  kable_styling(bootstrap_options = "striped", full_width = F, position = "left")
```

build_report.R

# Libraries
require(knitr)
require(markdown)
library(RMySQL)
library(png)
library(kableExtra)

# create .md file
knit("template.Rmd", "template.md")

# create .pdf file
command <- paste0("pandoc -V geometry:'left=0.5in,bottom=1in,top=1.5in' -s ", "template.md", " -o ", "output.pdf")
system(command)

作法：在左侧Markdown PDF对齐表格
