使图像用作shinydashboard的标题正好适合标题框

我把一个图像作为我闪亮的仪表板的标题,我已经调整了它的大小,以适应高度和宽度,但在左侧有一个小部分仍然是空的。我怎样才能使它正好放在盒子里?(附加图像的蓝色部分仍为空)

# app.R ##
library(shiny)
library(shinydashboard)
library(shinydashboardPlus)
library(DT)
library(shinyWidgets)
library(shinyjs)

dbHeader <- dashboardHeaderPlus(
  enable_rightsidebar = TRUE,
  rightSidebarIcon = "gears",
  fixed = T,
  title = tags$a(href='http://mycompanyishere.com',
                                 tags$img(src='logo.png',height = "55px",width="232px"))
)

ui <- dashboardPagePlus(
  dbHeader,
  dashboardSidebar(),
  dashboardBody(
    useShinyjs(),
    tags$hr(),
    tabsetPanel(
      id ="tabA",
      type = "tabs",
      tabPanel("Front",icon = icon("accusoft")),
      tabPanel("Data", icon = icon("table")
      )
    )
  ),
  rightsidebar = rightSidebar()
)

server <- function(input, output) {

}

shinyApp(ui = ui, server = server)
