R Shiny：以绝对面板为中心

Question

如何将一个绝对面板置于Shiny的中心？我尝试过设置左= 50％并将其放在面板的左侧。

Option Explicit
Private WithEvents ExcelApp As Excel.Application

Private Sub ExcelApp_NewWorkbook(ByVal Wb As Workbook)
    If Wb.Name = "MyWorkbook.xlsm" Then Call ProcessMyWorkbook
End Sub

Private Sub Workbook_Open()
    Set ExcelApp = Application
End Sub

Answer 1

经过一些实验，这很有效。在absolutePanel内（在ui.R中）设置

absolutePanel(id = "myId", class = "myClass", fixed = TRUE
                ,draggable = TRUE, top = 0, left = 0, right = 0, bottom = 0
                ,width = 100, height = "auto", ...

然后在css文件集中

#myId { 
  margin: auto;
}

Answer 2

我认为你应该把它放在css文件中：

#myId{margin: auto;}
