R Markdown表格标题宽度(带有线和长桌) [英] R Markdown table caption width with kable and longtable
问题描述
使用R Markdown输出pdf. kable()效果很好，但是当我添加longtable=T时，标题不再扩展表格的整个宽度.我似乎找不到在此处控制字幕详细信息的参数.我可以将标题移动到每个代码块，但如果可能的话，宁愿使用kable中的内置功能.</p>
谢谢！

这可能是longtable软件包中的LaTeX问题.本页提出了一种解决方法: https://tex.stackexchange.com/Questions/287283/如何定义字幕在长表中的宽度.刚放
header-includes:
- \usepackage{caption}
在您的YAML标头中，一切将按您预期的方式工作.您还可以添加LaTeX代码
\captionsetup{width=5in}
(或使用其他度量，例如5cm，\textwidth，\textheight等)来获得其他尺寸的字幕宽度一致.
编辑后添加:
这是原始示例，根据建议进行了修改(还有更多清理工作):

```{r setup, include=FALSE}

Add `\captionsetup{width=5in}` on its own line here for smaller captions.
```{r table1}
test <- data.frame(col1=rep("MyLongWordsareLong",5),
col2=rep("MyLongWordsareLong",5),
col3=rep("MyLongWordsareLong",5),
col4=rep("MyLongWordsareLong",5),
col5=rep("MyLongWordsareLong",5),
col6=rep("MyLongWordsareLong",5))
kable(test,format='latex',booktabs=TRUE,
caption="This is my example caption. See how, when I don't use
longtable, it extends the full width of the table, but when I use the
longtable option, it compresses down to only a portion of the table's wdith.
Is this weird or is it just me?") %>%
landscape()
kable(test,longtable=TRUE,format='latex',booktabs=TRUE,caption="This is my
example caption. See how, when I don't use longtable, it extends the full
width of the table, but when I use the longtable option, it compresses down

landscape()
```
这是它生成的两个表:
Using R Markdown to output a pdf. kable() works great but when I add longtable=T the caption no longer extends the full width of the table. I can't seem to find an argument that will control the caption details here. I can move the caption to be output for each code chunk but would rather use the built in functionality within kable if possible.
Thanks!

This is probably a LaTeX problem in the longtable package. This page suggests a workaround: https://tex.stackexchange.com/questions/287283/how-to-define-caption-width-in-longtable . Just put
header-includes:
- \usepackage{caption}
in your YAML header, and things will work the way you expected. You can also add the LaTeX code
\captionsetup{width=5in}
(or use some other measure, such as 5cm, \textwidth, \textheight, etc.) to get consistent caption widths of other sizes.
Edited to add:
Here's the original example, modified as suggested (plus a little bit more cleanup):

Add `\captionsetup{width=5in}` on its own line here for smaller captions.
```{r table1}
test <- data.frame(col1=rep("MyLongWordsareLong",5),
col2=rep("MyLongWordsareLong",5),

kable(test,format='latex',booktabs=TRUE,
caption="This is my example caption. See how, when I don't use
longtable, it extends the full width of the table, but when I use the
longtable option, it compresses down to only a portion of the table's wdith.

Here are the two tables it produces:
