For a client side solution

So run this code after the first block of code, it rewrites the final two columns.

Sub Test2()
    '* tools references ->
    '*   Microsoft HTML Object Library


    Dim oHtml4 As MSHTML.IHTMLDocument4
    Set oHtml4 = New MSHTML.HTMLDocument

    Dim oHtml As MSHTML.HTMLDocument
    Set oHtml = Nothing

    '* IHTMLDocument4.createDocumentFromUrl
    '* MSDN - IHTMLDocument4 createDocumentFromUrl method - https://msdn.microsoft.com/en-us/library/aa752523(v=vs.85).aspx
    Set oHtml = oHtml4.createDocumentFromUrl("https://rasmusrhl.github.io/stuff/", "")
    While oHtml.readyState <> "complete"
        DoEvents  '* do not comment this out it is required to break into the code if in infinite loop
    Wend
    Debug.Assert oHtml.readyState = "complete"


    Dim oTRs As MSHTML.IHTMLDOMChildrenCollection
    Set oTRs = oHtml.querySelectorAll("TR")
    Debug.Assert oTRs.Length = 17

    Dim lRowNum As Long
    For lRowNum = 3 To oTRs.Length - 1

        Dim oTRLoop As MSHTML.HTMLTableRow
        Set oTRLoop = oTRs.Item(lRowNum)
        If oTRLoop.ChildNodes.Length > 1 Then

            Debug.Assert oTRLoop.ChildNodes.Length = 14

            Dim oSecondToLastColumn As MSHTML.HTMLTableCell
            Set oSecondToLastColumn = oTRLoop.ChildNodes.Item(12)

            ActiveSheet.Cells(lRowNum + 2, 13).Value2 = "'" & oSecondToLastColumn.innerText


            Dim oLastColumn As MSHTML.HTMLTableCell
            Set oLastColumn = oTRLoop.ChildNodes.Item(13)

            ActiveSheet.Cells(lRowNum + 2, 14).Value2 = "'" & oLastColumn.innerText

        End If
        'Stop

    Next lRowNum

    ActiveSheet.Columns("M:M").EntireColumn.AutoFit
    ActiveSheet.Columns("N:N").EntireColumn.AutoFit


End Sub

For a Server Side Solution

Now that we know you control the source script and that it is in R then one can change the R script to style the final columns with mso-number-format:'\@' . Here is a sample R script that achieves this, one builds a CSS matrix of the same dimensions as the data and passes the CSS matrix as a parameter into htmlTable. I have not tampered with your R source instead I give here a simple illustration for you to interpret.

A=matrix(c("(2)","(4)","(3)","(1)","(5)","(7)"),nrow=2,ncol=3,byrow=TRUE)
css_matrix <- matrix(data="",nrow=2,ncol=3)
css_matrix[,3] <- "mso-number-format:\"\\@\""
htmlTable(x=A,css.cell=css_matrix)

Opening in Excel I get this

Robin Mackenzie adds

you might mention in your server-side solution that OP just needs to add css_matrix[,10:11] <- "mso-number-format:\"\@\"" to their existing R code (after the last css_matrix... line) and it will implement your solution for their specific problem

Thanks Robin
