Stores the hash args
containing styling properties for the cells specified via the given 0-based rows and columns.
Rows and columns can either be single numbers, ranges of numbers or stepped ranges (i.e. Enumerator::ArithmeticSequence instances).
Examples:
# Gray background for all cells
args[] = {cell: {background_color: "gray"}}
# Cell at (2, 3) gets a bigger font size
args[2, 3] = {font_size: 50}
# First column of every row has bold font
args[0..-1, 0] = {font: 'Helvetica bold'}
# Every second row has a blue background
args[(0..-1).step(2)] = {cell: {background_color: "blue"}}
Retrieves the merged keyword arguments for the cell in row
and col
.
Earlier defined arguments are overridden by later ones, except for the :cell
key which is merged.
