我在Shiny中创建了一个数据表,该数据表使用DT基于一组隐藏列中的值来设置值的样式。该表显示公司的部门是否达到了呼叫和电子邮件的目标。
问题在于,当我隐藏列(使用columnDefs = list(list(targets = c(4, 5), visible = FALSE))
)时,无法再在rownames = FALSE
调用下使用datatable()
:该表显示为无数据。有谁知道我如何才能同时使用这两个选项?
我使用了以下文章:

How do I suppress row names when using DT::renderDataTable in R shiny?
library(shiny)
library(tidyverse)
library(DT)
x <- tibble(
Unit = c("Sales", "Marketing", "HR"),
Calls = c(100, 150, 120),
Emails = c(200, 220, 230),
Calls_goal = c(1, 0, 0),
Emails_goal = c(0, 1, 1)
)
ui <- fluidPage(
mainPanel(
DT::dataTableOutput("table")
)
)
server <- function(input, output) {
output$table <- DT::renderDataTable({
# Can't use both visible = FALSE and rownames = FALSE
datatable(x,
options = list(
columnDefs = list(list(targets = c(4, 5), visible = FALSE)) # THIS
),
rownames = TRUE) %>% # OR THIS
formatStyle(
columns = c('Calls', 'Emails'),
valueColumns = c('Calls_goal', 'Emails_goal'),
color = styleEqual(c(1, 0), c("red", "black"))
)
})
}
shinyApp(ui = ui, server = server)
答案 0 :(得分:1)
由于行名也是一列,因此将它们设置为false时,您需要为要隐藏的列重新索引。因此,在您的特定情况下,第5列不再存在。现在它是4号,而4号是3号,因此您的代码应如下所示:
def sum_vals(num1, num2):
result = sum(range(num1, num2))
print(result)
sum_vals(3, 7)
