使html表列更宽/防止单词在RMarkdown中换行 [英] Make html table columns wider / prevent words from wrapping in RMarkdown
问题描述
我正在创建带有R降价的html文档，其中包含一些表格.在表的一列具有字符值的情况下，如何确保该列足够宽以包含整个字符串而无需换行?我尝试在下面使用kableExtra，但即使bold参数被使用，似乎也没有使用column_spec的width参数.
I'm creating an html document with R markdown which has some tables. In situations where one column of a table has character values, how can I ensure the column is wide enough to contain the entire character string without wrapping? I tried using kableExtra below, but it seems like the width argument of column_spec is not being used even though the bold argument is.

推荐答案
我认为这更像是HTML/css问题.当HTML表的宽度超过页面宽度时，如有必要，它将尝试减小列宽.如果减少csd的列数，您将看到width选项开始显示效果.
I think it's more like an HTML/css issue. When the width of an HTML table exceed the page width, it will try to reduce column width if not necessary. If you reduce the number of columns for csd, you will see the width option starts to show an effect.
在这种情况下，一种解决方法是使用scroll_box函数并为表格提供更大的绘图区域.
In this case, one way to work around is to use the scroll_box function and give the table a wider plotting area.
csd %>%
kable('html', digits = 2) %>%
column_spec(1, bold = T, width = "2600em") %>%
kable_styling(bootstrap_options = c("striped", "hover")) %>%
scroll_box(width = "2000px")
更新
另一种骇人听闻但真实"的解决方案是强制将单元格显示为嵌入式块
Another hacky but "real" solution is to force the cell display as an inline-block
csd %>%
kable('html', digits = 2) %>%
column_spec(1, bold = T, width = "2600em; display: inline-block;") %>%
kable_styling(bootstrap_options = c("striped", "hover"))
更新
display: inline-block现在默认包含在kableExtra(dev ver)中.
The display: inline-block thing is now included by default in kableExtra (dev ver).
如果默认情况下为display: inline-block;，则表列的标题行将失去自动调整其宽度的能力.当表又小又紧时，它会破坏column_spec.结果，我将默认删除此行.如果需要强行设置宽度.您可以随时使用我上面提供的方法.
If we have display: inline-block; by default, the header row of the table columns lost the ability to adjust its width automatically. It breaks column_spec when the table is small and tight. As a result, I'm removing this line from default. If you need to forcefully set the width. you can always use the method I provided above.
