# All of the previous styling options we've seen deal with all the table cells
# at once.
#
# With initializer blocks we may deal with specific cells.
# A block passed to one of the table methods (<code>Prawn::Table.new</code>, <code>Prawn::Document#table</code>,
# <code>Prawn::Document#make_table</code>) will be called after cell setup but
# before layout. This is a very flexible way to specify styling and layout
# constraints.
#
# Just like the <code>Prawn::Document.generate</code> method, the table initializer
# blocks may be used with and without a block argument.
#
# The table class has three methods that are handy within an initializer block:
# <code>cells</code>, <code>rows</code> and <code>columns</code>. All three
# return an instance of <code>Prawn::Table::Cells</code> which represents
# a selection of cells.
#
# <code>cells</code> return all the table cells, while <code>rows</code> and
# <code>columns</code> accept a number or a range as argument which returns a
# single row/column or a range of rows/columns respectively. (<code>rows</code>
# and <code>columns</code> are also aliased as <code>row</code> and
# <code>column</code>)
#
# The <code>Prawn::Table::Cells</code> class also defines <code>rows</code> and
# <code>columns</code> so they may be chained to narrow the selection of cells.
#
# All of the cell styling options we've seen on previous examples may be set as
# properties of the selection of cells.
