DB & Dev Tools · Databases: the structure editor stacks in a narrow box

TableStructureEditor measures its width. With room for its least width
it lines the fields up as a table whose cells take fixed shares of that
width, so what they hold is measured at its final width; in a narrower
box each field stacks on its own, its name and remove button, its type
with its flags, then its default, all inside the box. No sideways
scroll remains, so no Tab stop lies past a fold. Tests cover both.
