I have a table where each row might have one, two or three columns. For example, here is a similar table I made in LibreOffice Writer, using the split cell functionality: As far as I can tell, Google Documents does not have "Split cell", only "Merge cell".
So I can do this by creating a table with six columns, then merging the appropriate combinations. However, this is fiddly and manual.
Is there a better way?
