Crystal Reports allows you to add
lines to a report to emphasize important data and create professional-looking
reports. Lines can run horizontally or vertically. For a vertical line to be
broken across several pages, the report section that the line ends in must not
be on the same page that it starts on. For example, if a line runs from a group
header to the corresponding group footer, the line continues on the top of each
subsequent page—just below the page header—until the group footer is
encountered.
