r - 为什么在 Shiny 中列不跨页面分布？

Question

我认为整行是 12，所以 4 个 3 宽的列应该填满整个页面，但事实并非如此。图书馆（闪亮）

fluidPage(

    mainPanel(

      fluidRow(
        column(3,
               textInput("user_id", "User ID", width = NULL)
        ),

        column(3,
               textInput("name", "Organization name",value = "",width = NULL)
        ),
        column(3,

               textInput("address", "Address",value = "",width = NULL)
        ),
      column (3,
              textInput("zip", "Zip Code",value = "",width = NULL)
      )

      ) #row

    ) #panel

  ) #page

默认情况下mainPanel有width8 个。查看文档时可以看到：

?shiny::mainPanel

主面板（...，宽度 = 8）

width = 12因此，您必须在mainPanel通话中明确说明。

fluidPage(

    mainPanel(

      fluidRow(
        column(3,
               textInput("user_id", "User ID", width = NULL)
        ),

        column(3,
               textInput("name", "Organization name",value = "",width = NULL)
        ),
        column(3,

               textInput("address", "Address",value = "",width = NULL)
        ),
      column (3,
              textInput("zip", "Zip Code",value = "",width = NULL)
      )

      ) #row

    , width = 12) #panel

  ) #page

..应该做的伎俩。
