Shiny and Batch file

The app works fine, but when I try to open it by a Batch file the app doesn't show me the table in the exact width and font-size. How can I solve it? Is it possible?

div(DT::dataTableOutput("macroTableUp"), style = "font-size: 79%; width: 79%"))

The app opened by Batch file show me the table with font-size and width as 100%
