如何使用rmarkdown和pandoc在表中编写多级（项目符号）列表

Question

我正在使用rmarkdown，knitr和pander在PDF文档中创建表格。我可以创建一个simple bullet list，但现在需要该列表中的另一个级别。在下表中，我要求“ Rave reviews”项目符号是“ Offers workshops ...”项目符号的子项目符号。

我遇到的问题与mytable列中Description数据框中的以下代码行有关。尽管我尝试使用\x20 [1]创建子项目符号所需的4个空格，但这些空间不会出现-因此没有子项目符号（尽管未显示错误）。我还尝试了最简单的方法，简单地在代码中添加4个空格无济于事。还尝试将我的R选项设置为包括strip.white = FALSE，但这也没有被证明有用（请参阅下文）。

---
title: "xxx"
author: "xxx"
output:
  pdf_document:
    fig_height: 4
    fig_width: 10
    highlight: tango
  word_document: default
geometry: margin=3cm
---

```{r global_options, include=FALSE, echo=FALSE}
require(knitr)
opts_chunk$set(fig.width=8, fig.height=4, fig.path='figs/', dpi=500,
               echo=FALSE, warning=FALSE, message=FALSE, results='hide', strip.white = FALSE)
```

```{r pandoc_options, include=FALSE, echo=FALSE}
require(pander)
panderOptions('digits', 3)
panderOptions('round', 3)
panderOptions('keep.trailing.zeros', TRUE)
panderOptions('keep.line.breaks', TRUE)
```

```{r concepts, echo=FALSE}
mytable = data.frame(
    Concept     = c("Decoded", "XXX"),
    Description = c("* Founded in 2011\ \n* Offers workshops to take people from zero skills and knowledge in programming through to coding a multi-platform app using HTML, CSS and Javascript in a single day\ \n\x20\x20\x20\x20+ Rave reviews", "XXX"),
    Website     = c("http://decoded.com/uk/","XXX"))
```

``` {r concepts_descriptions, results = 'asis'}
pander::pander(mytable, keep.line.breaks = TRUE, style = 'grid', justify = 'left')
```

[[1]在尝试\x20，here，\\s，\s等无济于事（建议\ \s）后，我从\\\s获得了here提示。

Answer 1

您可以将项目嵌套在项目符号内：

```{r concepts, echo=FALSE}
mytable = data.frame(
    Concept     = c("Decoded", "XXX"),
    Description = c("* Founded in 2011\ \n
    * Offers workshops to take people from zero skills and knowledge in programming through to coding a multi-platform app using HTML, CSS and Javascript in a single day\ \n
    \\begin{itemize}
      \\item Rave reviews \n
      \\item e.t.c
    \\end{itemize}", "XXX"),
    Website     = c("http://decoded.com/uk/","XXX"))
```

编辑：我没有意识到您使用的是pdf，但这是html解决方案

1. 我会使用矩阵
2. 我将使用htmlTable包，该包允许使用比kable或pander更高级的表

首先为您的列表制作包装器

make_list <- function(...) {
  paste0("<ul>", sprintf('<li>%s</li>', substitute(...())), '</ul>', collapse = '')
}

make_list(one, two, three)

# [1] "<ul><li>one</li></ul><ul><li>two</li></ul><ul><li>three</li></ul>"


library('htmlTable')
mytable <- matrix(c("Decoded", "XXX",
                    make_list('Founded in 2011', 'Offers workshops to take people from zero skills and knowledge in programming through to coding a multi-platform app using HTML, CSS and Javascript in a single day','Rave reviews'),
                    "XXX",
                    "http://decoded.com/uk/","XXX"), 2,
                  dimnames = list(NULL, c('Concept','Description','Website')))

htmlTable(mytable, align = 'lll')

<< img src =“ https://image.soinside.com/eyJ1cmwiOiAiaHR0cHM6Ly9pLnN0YWNrLmltZ3VyLmNvbS9qNElLYi5wbmcifQ==” alt =“在此处输入图像描述”>

这很好，但是垂直对齐不好，并且框太宽。但是我们可以使用htmlTable的css参数之一进行修复。垂直对齐将文本推到顶部而不是中心，max-width设置文本换行，自动宽度让每个文本都有自己的宽度

htmlTable(mytable, align = 'lll', align.header = 'lll',
          css.cell = "width: auto; max-width: 250px; vertical-align: top;")
