SpanLineThickness
is an option for selections that specifies the thickness in printer's points of line-spanning characters such as \[VerticalLine] and \[HorizontalLine].

With the default setting SpanLineThickness->Automatic, the thickness of line-spanning characters is set to an appropriate default value.

With the setting SpanLineThickness -> k, the thickness of a line-spanning character is k times its thickness in the default font.
