__doc__="""
Tables are created by passing the constructor a tuple of column widths, a tuple of row heights and the data in
row order. Drawing of the table can be controlled by using a TableStyle instance. This allows control of the
color and weight of the lines (if any), and the font, alignment and padding of the text.

None values in the sequence of row heights or column widths, mean that the corresponding rows
or columns should be automatically sized.

All the cell values should be convertible to strings; embedded newline '\\n' characters
cause the value to wrap (ie are like a traditional linefeed).

See the test output from running this module as a script for a discussion of the method for constructing
tables and table styles.
