May I ask for help regarding a specific kind of justifying paragraph

Hi, I might get some hate and confusion for this, but I noticed with 'set fi=
ll', I can modify column justification of paragraphs. How can I do this with=
 rows?

simple example:

this is some text:
function apple {
    echo "done"
}

this is what happens normally after I justify:
function apple {echo "done"
{

this is what I want:
function apple {echo "done"}

Thanks for reading.=20=
