R dt 问题：数据表顶部过滤器

Question

这可能是一个非常简单的问题，但我仍然很困惑，似乎无法在 stackoverflow 中找到类似的问题。 我有以下示例数据框：

df2 = data.frame(RTG=c("A+","A+","AA","AA"),CITY=c("A","B","C","D"), stringsAsFactors = T)

然后，我创建以下数据表：

datatable(df2, 
          rownames= T,
          colnames = T,
          filter = c('top'),
          extensions = "Buttons", 
          options = list(scrollX = T
                         , lengthChange = T
                         , paging = T    
                         , autoWidth = F
                         , pageLength = T 
                         , dom = 'Blfrtip'
                         , info = T 
                         , searching = F
          ))

如果我使用 RTG 过滤器并选择“AA”，也会显示 RTG =“A+”的行。这对我来说似乎没有意义。我缺少什么？ 谢谢你

通过设置选项

searching = F

，您完全停用了搜索功能。如果您想删除整个表的搜索字段，同时保留列过滤器，只需从

dom

选项中删除“f”即可。

  df2 = data.frame(RTG=c("A+","A+","AB","AA"),CITY=c("A","B","C","D"), stringsAsFactors = T)


DT::datatable(
  df2,
  rownames = T,
  colnames = T,
  filter = list(position = 'top'),
  extensions = "Buttons",
  options = list(
    scrollX = T,
    lengthChange = T,
    paging = T,
    autoWidth = F,
    pageLength = 5,
    dom = 'Blrtip',
    info = TRUE,
    dom = `t`
  ))
