Styles

• The stylist is a callback routine that can deliver a hash ref with additional layout properties for rows, columns and cells.

• Rows can be identified by the (optional) _style.

• Columns can be identified by the name.

• This makes it possible to identify each individual cell of the report.

• For example, if you want a line before the row with style total, the stylist can return { line_before => 1 } when called for the given row.
