When you enable the grid lines for printing in Format > Page > Sheet tab they get a thin black appearance by default. I would like to be able to change either their thickness/width to make them thicker, and/or their colour to make them dark grey instead of black.
For the colour I’ve tried in Options > Libreoffice > Appearance > Spreadsheet section by changing the colour of Grid lines from automatic to something else but they only change in the spreadsheet and not when printing or exporting to pdf. Even in the print preview they still remain black.
For the width/thickness I haven’t found any setting or place to do so.
I’m aware of borders and their customization options but I would like to know about if black thin lines is the only option when you choose to print grid lines or if there is a way to change those.
