关闭可调整大小的rhandsontable

Question

我正在使用rhandsontable创建一个供用户编辑的表。我注意到，如果将右下角的框拖过最后一个框，则可以调整数据框的大小。是否有选项或解决方案可以关闭可调整大小的数据帧？

library(shiny)
library(rhandsontable)

server = (function(input, output, session) {

output$hot = renderRHandsontable({
    DF = data.frame(val = 1:10, bool = TRUE, big = LETTERS[1:10],
                small = letters[1:10],
                dt = seq(from = Sys.Date(), by = "days", length.out = 10),
                stringsAsFactors = FALSE)

rhandsontable(DF, readOnly = TRUE, width = 550, height = 300) %>%
  hot_col("val", readOnly = FALSE)
  })
})

ui = (fluidPage(
  rHandsontableOutput("hot")
))

shinyApp(ui = ui, server = server)
