The \vline command will draw a vertical line extending the full height and depth of its row. An \hfill command can be used to move the line to the edge of the column. It can also be used in an @-expression.
Prikaz \vline namaluje svislou caru pres celou vysku radku.
Prikazem \hfill lze tuto caru posunout na hranu sloupce.
Toto lze pouzit i v @-vyrazech.
