我确定没有人帮助过我，tk。我只是 asked the question之前不是很正确。 我正在尝试创建一个 FlexDashcoard 应用程序。要了解该程序的工作原理，您需要 sample data files我已经准备好了。对于文件中的俄语字符，我提前表示歉意，它们是“按原样”呈现给您的。
这是我的代码:

output:
flexdashboard::flex_dashboard:

vertical_layout: fill

```{r GlobalOptions}
options(knitr.duplicate.label = 'allow')
rv <- reactiveValues(txt_file = FALSE)
OKVEDselectInputChoices<- reactiveValues(data = NULL)
```
```{r setup, include=FALSE, echo=FALSE, message=FALSE}

### Basic information
```{r}
#renderTable({
# dataset <- rv_result()
# dataset
#})
f <- function(verlist, list_for_ver, resulttyp=0,delna=1) {
# verlist - массив, который требуется проверить на совпадение с элементами второго массива
# list_for_ver - проверочный массив, т.е. тот, с которым сравнимается
# resulttyp (0 - выводятся номера элементов list_for_ver, которые найдены);
# (1 - выводятся найденные значения)
# delna - (0 -если элемент не найде, то он не показывается)
# (1 -если элемент не найде, то указывается NA)
listforreturn <- vector(mode = 'list', length=0)
if ((class(verlist)=='list') && (class(list_for_ver)=='list')){
if (delna==1){
listforreturn <- as.vector(na.omit(match(verlist,list_for_ver)))
}
else{
listforreturn <- as.vector(match(verlist,list_for_ver))
}
if (resulttyp==0){
listforreturn <- as.list(listforreturn)
}
else{
listforreturn<- as.list(list_for_ver[listforreturn])
}
}
return(listforreturn)
}
dataset <- reactive({rv_result()})
renderUI({
data <- dataset()
if (is.null(input$OKVEDlectInput)) {
data <- dataset()
}
else{
d1 <- as.list(input$OKVEDlectInput)
d2 <- as.list(as.vector(data$V5))
result <- which(!is.na(f(d2, d1,0,0)))
result <- as.vector(result)
data <- data[result,]
}
div(HTML("География анлиза насчитывает "),
datatable(data, fillContainer=getOption("DT.fillContainer", TRUE)))
})
```
### Secondary information
Some commentary about Frame 2.You can download the finished version of the code
我的应用程序首先创建一个界面，允许用户选择要导入的文件(或多个)，但具有特定名称，并将这些数据加载到应用程序中。
在这一行中，我创建了一个映射:
div(HTML("География анлиза насчитывает "),
datatable(data, fillContainer=getOption("DT.fillContainer", TRUE)))
看起来很奇怪。如果不添加fillContainer=getOption("DT.fillContainer", TRUE)，则滚动条从表格中消失。当您添加此元素时，所有内容都会缩小到非常窄的尺寸:
我无法将表格拉伸(stretch)到底部以获得剩余的可用空间。
我特地准备了一个简短版的代码，从中可以看出问题是亲切的，使用现成的数据数组很容易重复。

### Chart A

renderUI({
data <- iris
div(HTML("География анлиза насчитывает "),
datatable(data, fillContainer=getOption("DT.fillContainer", TRUE)))
})
```最佳答案
您可以使用 css 来增加/减少数据表的宽度和高度。我在 div 中添加了 style = "height: 175%" 以增加高度。
