How to put the column and line on the screen

Are you wishing to open these documents in LO?;
            LO probably will open them without any changes.
OR
       Are you wishing to save previously made documents in LO for future
use?;
            if so, then as you familiarize yourself with the menu options,
at the top, select the various settings.
           [you could go on-line & read the manual pages; as for me, I
stick with the KIS method :wink: ]

       Hoping this helps,
