I need to place an image behind my table in calc, so after adding an image i click on it with right mouse button, next i choose “Arrange” and next “To Background”. After that all looks great - image is behind the whole table.
Next i choose File->Save As… and choose file type “.xls”. Next i close this document and instantly open this document again and image is front of all, so i see only image and not my table.
I use LibreOffice 18.104.22.168
