使用 Shiny 中的 Datatable 创建文本换行和管理列宽
Create text wrap and manage column width with Datatable in Shiny
我有一个数据 table,其中有很多文字。我想以一种易于阅读的方式组织它。我尝试了一些想法,但它们似乎没有用。我也乐于接受有关如何组织数据的任何建议 table.
这是我试图控制列宽的代码。现在宽度非常宽,我想将选定的列缩小很多。
output$newsfeed = renderDataTable({
datatable(df, rownames = F, extensions = "Scroller",
options = list(deferRender = TRUE,
scrollY = 400,
scrollX = TRUE,
scroller = TRUE,
autoWidth = TRUE,
columnDefs = list(list(width = '50px', targets = list(1,2,3,4,5)))
))
})
感谢您的帮助。
尝试对感兴趣的列使用 width = '10%'
。
library(DT)
library(shiny)
dat <- data.frame(
V1 = c("A", "B"),
V2 = c(
"A cool guy living in US and Canada",
"A cool guy living in New York"
),
V3 = c(
"A cool guy living in US and Canada",
"A cool guy living in New Jersey"
),
V4 = c(
"A cool guy living in US and Canada",
"A cool guy living in California"
),
V5 = c(
"A cool guy living in the US and else where",
"A cool guy living in Texas"
),
stringsAsFactors = FALSE
)
ui <- fluidPage(
DTOutput("table")
)
server <- function(input, output){
output[["table"]] <- renderDT({
datatable(dat, options = list(
deferRender = TRUE,
scrollY = 400,
scrollX = TRUE,
scroller = TRUE,
autoWidth = TRUE,
columnDefs = list(list(width = '10%', targets = c(2,3,4)))
)) # %>% formatStyle(columns = c(2,3), width='20px')
})
}
shinyApp(ui, server)
我猜 'extensions = "Scroller"' 控制列宽发生冲突。
当我将 'extensions = "Scroller"' 添加到 YBS 的代码时,文本不会换行。
