class TaskJuggler
# The ReportTableColumn class models the output format independend column of a
# ReportTable. It usually just contains the table header description. The
# table header comprises of one or two lines per column. So each column header
# consists of 2 cells. @cell1 is the top cell and must be present. @cell2 is
# the optional bottom cell. If @cell2 is hidden, @cell1 takes all the vertical
# space.
#
# For some columns, the table does not contain the usual grid lines but
# another abstract object that responds to the usual generator methods such as
# to_html(). In such a case, @cell1 references the embedded object via its
# special variable. The embedded object then replaced the complete column
# content.
class ReportTableColumn
attr_reader :definition, :cell1, :cell2
attr_accessor :scrollbar
# Create a new column. _table_ is a reference to the ReportTable this column
# belongs to. _definition_ is the TableColumnDefinition of the column from
# the project definition. _title_ is the text that is used for the column
# header.
def initialize(table, definition, title)
@table = table
# Register this new column with the ReportTable.
@table.addColumn(self)
@definition = definition
# Register this new column with the TableColumnDefinition.

# Create the 2 cells of the header.

@cell1.padding = 5
@cell2 = ReportTableCell.new(nil, nil, '', true)
# Header text is always bold.
@cell1.bold = @cell2.bold = true
# This variable is set to true if the column requires a scrollbar later
# on.

# of Strings. We have an Array with Strings for every cell. The outer Array
# holds the Arrays representing the lines.
