Sort the rows
Sort by one or more columns, ascending or descending.
order=nameorder=estimate.descorder=estimate.asc.nullsfirstorder=owner.name,steps.count.descEach term is a column with asc (the default) or desc, then optionally nullsfirst or nullslast. Without those, nulls come last going up and first going down, on every database.
You can sort by a to-one related column, like owner.name, and by how many related rows a to-many relation has, like steps.count.
The key is always added as a last term, so rows that tie keep the same order from one page to the next.
