R：突出显示数据表中的行的问题

Question

我最近一直在学习flexdashboard制作仪表板。我正在尝试将特定行设置为 bold，但如果我将 rownames 设置为 False，它将无法正常工作。这是一个例子：

# This example sets the 3rd row to bold
df <- data.frame(
a = runif(3),
b = runif(3),
c = runif(3))
library(DT)
df %>%
  datatable(rownames = T,
            options = list(pageLength = 3,
                         searching = F,
                         lengthChange = F,
                         info = F,
                         paging = F,
                         ordering = F,
                         columnDefs = list(list(className = 'dt-center', targets = 0:3)))) %>% 
  formatStyle(
  0,
  target = "row",
  fontWeight = styleEqual(3, "bold"))

如果rownames = F，上面的例子将不起作用。我不想显示 rownames。是什么原因，我该如何解决？

关闭行名称会删除您引用的索引以突出显示该行。所以我们需要创建自己的：

df$index <- seq(1,3)

然后，我们创建 datatable，并在 columnDefs

中使用 list(visible = FALSE, targets = c(3)) 隐藏 df$index

df %>%
  datatable(rownames = F,
            options = list(pageLength = 3,
                         searching = F,
                         lengthChange = F,
                         info = F,
                         paging = F,
                         columnDefs = list(list(className = 'dt-center', targets = 0:2), list(visible=FALSE, targets = c(3))))) %>% 
  formatStyle('index',
  target = "row",
  # this says 'style rows bold where index == 3'
  fontWeight = styleEqual(3, "bold"))
