Question

我有以下自己包含Shiny-Flexdashboard：

---
title: "FOO"
runtime: shiny
output: 
  flexdashboard::flex_dashboard:
    vertical_layout: scroll
    orientation: rows
    theme:   default

---

```{r setup, include=FALSE}
library(flexdashboard)
library(tidyverse)
```

Rows
-------------------------------------

### Statistical Test Summary
```{r stat_test_table}
mainPanel(

  renderTable( {
      dat <- df <- structure(list(`Sample name` = structure(1:3, .Label = c("Sample1", 
          "Sample2", "Sample3"), class = "factor"), `FDR correction (mean)` = c(5.93070861978308e-15, 
         6.88632524238004e-13, 3.28339498763286e-16), `FDR correction (sd)` = c(2.00046170407461e-14, 
        2.32019633515427e-12, 1.10782095003689e-15), `P-value (mean)` = c(5.55365134900322e-15, 
        6.44757191496266e-13, 3.07475941705412e-16), `P-value (sd)` = c(1.98732517127302e-14, 
        2.30494707691577e-12, 1.10054774779699e-15)), class = c("tbl_df", 
        "tbl", "data.frame"), .Names = c("Sample name", "FDR correction (mean)", 
        "FDR correction (sd)", "P-value (mean)", "P-value (sd)"), row.names = c(NA,  -3L))
  }
  , digits=-2, width = '100%'
  )
)
```

它产生这样的表：

如上所述，我如何扩展列宽？

Answer 1

有趣。如果你看一下?mainPanel()的文件。您将看到宽度默认限制为＆＃34; 8＆＃34; （12是最大值）： mainPanel(..., width = 8)

所以，如果你简单地改为： mainPanel(..., width = 12)它会起作用。

Answer 2

在width = 12中使用mainPanel并在div内附上表格就可以了。

  renderTable( {
      dat <- df <- structure(list(`Sample name` = structure(1:3, .Label = c("Sample1", 
          "Sample2", "Sample3"), class = "factor"), `FDR correction (mean)` = c(5.93070861978308e-15, 
         6.88632524238004e-13, 3.28339498763286e-16), `FDR correction (sd)` = c(2.00046170407461e-14, 
        2.32019633515427e-12, 1.10782095003689e-15), `P-value (mean)` = c(5.55365134900322e-15,

  }
  , digits=-2, width = '100%'

)
```

它产生的输出为：

Answer 3

我认为重要的是要注意mainPanel不是针对您的用例而设计的。这是＆＃34;正确的＆＃34; mainPanel的使用以及默认width = 8

的原因

sidebarLayout(
  sidebarPanel(sliderInput("thing", "Thing", min = 0, max = 5, value = 4)),
  mainPanel(
    renderDataTable( {

    input$Thing
      dat <- df <- structure(list(`Sample name` = structure(1:3, .Label = c("Sample1", 
          "Sample2", "Sample3"), class = "factor"), `FDR correction (mean)` = c(5.93070861978308e-15, 
         6.88632524238004e-13, 3.28339498763286e-16), `FDR correction (sd)` = c(2.00046170407461e-14, 
        2.32019633515427e-12, 1.10782095003689e-15), `P-value (mean)` = c(5.55365134900322e-15, 
        6.44757191496266e-13, 3.07475941705412e-16), `P-value (sd)` = c(1.98732517127302e-14, 
        2.30494707691577e-12, 1.10054774779699e-15)), class = c("tbl_df", 
        "tbl", "data.frame"), .Names = c("Sample name", "FDR correction (mean)", 
        "FDR correction (sd)", "P-value (mean)", "P-value (sd)"), row.names = c(NA,  -3L))
  }
  )
  )
)

此外，如果您使用DT :: renderDataTable，您可以更灵活地使用表格https://rstudio.github.io/DT/

实际上，默认情况下，这需要100％的浏览器窗口宽度而不需要包装器。您可以考虑在flexdashboards中使用fillPage和fluidPage来控制专用于各个元素的大小/区域。
