Shiny app excelR can t control table height

0 votes

I'm using ExcelR and Shiny. I can't seem to make the table bigger than say, 13 rows.

Here is an example code:

shinyApp(
    ui =  navbarPage("title", selected = "main", 
        position = "fixed-top", 
        tags$style(type="text/css", "body {padding-top: 70px;}"),
        tabPanel("main", id = "main",
            fluidPage(                
                excelOutput("table", width = "100%", height = "100%")
            )
        )
    ),
    server = function(input, output, session) {
        output$table <-renderExcel(
            excelTable(
                data = iris,
                autoColTypes = FALSE,
                pagination = 5,
                #autoFill = TRUE,
                fullscreen = FALSE,
                lazyLoading = TRUE,
                search = TRUE  
            )
        )
    }
)

When I turn on fullscreen, the remaining rows are presented but the search bar is hidden, and the spacing between the table and navbar is gone. Pagination appears to have no effect.

You can solve this by changing the excelTable function.

I added the line paramList$tableHeight <- "500px" to the function, and renamed the function excelTable2. I found this param on the website for jExcel: jExcel Parameters.

I guess I will probably add the height as an input parameter to excelTable2.

excelTable2 = function (data = NULL, columns = NULL, colHeaders = NULL, rowHeight = NULL, 
    nestedHeaders = NULL, defaultColWidth = NULL, minDimensions = NULL, 
    columnSorting = TRUE, columnDrag = FALSE, columnResize = TRUE, 
    rowResize = FALSE, rowDrag = TRUE, editable = TRUE, allowInsertRow = TRUE, 
    allowInsertColumn = TRUE, allowDeleteRow = TRUE, allowDeleteColumn = TRUE, 
    allowRenameColumn = TRUE, allowComments = FALSE, wordWrap = FALSE, 
    selectionCopy = TRUE, mergeCells = NULL, search = FALSE, 
    pagination = NULL, fullscreen = FALSE, lazyLoading = FALSE, 
    loadingSpin = FALSE, style = NULL, autoColTypes = TRUE, showToolbar = FALSE, 
    dateFormat = "DD/MM/YYYY", digits = 4, autoWidth = TRUE, 
    autoFill = FALSE, getSelectedData = FALSE, ...)

    paramList <- list()
    if (!is.null(data)) {
        if (is.data.frame(data) || is.matrix(data)) {
            paramList$data <- jsonlite::toJSON(data, dataframe = "values", 
                na = "null", digits = digits)
        }
        else {
            stop("'data' must be either a matrix or a data frame, cannot be ", 
                class(data))
        }
