无法在可达表格中呈现没有行计数的分组单元格

Question

我正在使用rMarkdown，编织成html，并试图在reactable中做一些简单的事情-使用JS在括号中隐藏行总计。我从他们自己的指南中抄袭，但这不起作用：

reactable Grouped Cell Rendering

data <- MASS::Cars93[10:22, c("Manufacturer", "Model", "Type", "Price", "MPG.city")]

reactable(
  data,
  groupBy = c("Manufacturer", "Type"),
  columns = list(
    Manufacturer = colDef(
      # Render grouped cells without the row count
      grouped = JS("function(cellInfo) {
        return cellInfo.value
      }")
    )
  )
)

我得到以下错误：

Error in colDef(grouped = JS("function(cellInfo) {\n return cellInfo.value\n }")) : 
unused argument (grouped = JS("function(cellInfo) {\n return cellInfo.value\n }"))

任何帮助都将不胜感激。

grouped参数在该程序包的CRAN版本上不可用。您可以从github安装开发版本，然后示例就可以工作了。

#install the package from github
#devtools::install_github("glin/reactable")
library(reactable)
data <- MASS::Cars93[10:22, c("Manufacturer", "Model", "Type", "Price", "MPG.city")]

reactable(
  data,
  groupBy = c("Manufacturer", "Type"),
  columns = list(
    Manufacturer = colDef(
      # Render grouped cells without the row count
      grouped = JS("function(cellInfo) {
        return cellInfo.value
      }")
    ),
    Type = colDef(
      # Render grouped cells with the row count, only if there are multiple sub rows
      grouped = JS("function(cellInfo) {
        if (cellInfo.subRows.length > 1) {
          return cellInfo.value + ' (' + cellInfo.subRows.length + ')'
        }
        return cellInfo.value
      }")
    )
  )
)
