如何减少DT数据表中的行高 [英] How can I reduce row height in DT datatables

问题描述

我希望能够在呈现 DT 数据表（即降低高度）时获得更细的行

I would like to be able to get 'slimmer' rows when rendering a DT datatable (ie decrease that height)

options(digits.secs=6)
library(data.table)
d = data.table(x = 1:10,time = as.POSIXct('2015-03-23 12:00:00.123'))
library(DT)
datatable(d)

推荐答案

如果添加 pageLength = 属性，您可以设置最初显示多少行。通过调整 lengthMenu = c（），您还可以控制下拉菜单中提供的尺寸，也可以使用打开或关闭搜索搜索= FALSE

If you add the pageLength= attribute you can set how many rows to show initially. And by adjusting the lengthMenu= c() you can also control the sizes of offered in the drop down, You can also turn search on or off with searching =FALSE

   library(DT)
    datatable(d, options=list(
       pageLength = 3,
       lengthMenu = c(2, 12, 18),
       searching= FALSE))%>%

   formatStyle( 0, target= 'row',color = 'black', backgroundColor = 'yellow', fontWeight ='bold', lineHeight='70%')

通过使用帮助器功能，您可以像在网页上的传统CSS中一样设置样式。注意最后一个，行高应该调整行高。

And by using the helper functions you can set the style just as you would in traditional CSS on a webpage. Notice the last one, line-height should adjust the row height.

编辑：我将所有代码移到一起，以了解其工作原理。抱歉，我没有事先弄清楚。 ％>％和DT的 devtools :: install_github（ rstudio / DT）版本一样是必需的。

Edited: I moved all the code together for you to see how it works. Sorry I was not clearer up front. The %>%is necessary as is devtools::install_github("rstudio/DT") version of DT.
