	Pretty-print tabular data.
	See also https://bitbucket.org/astanin/python-tabulate

	FILE                      a filename of the file with tabular data;
							  if "-" or missing, read data from stdin.

	Options:

	-h, --help                show this message
	-1, --header              use the first row of data as a table header
	-o FILE, --output FILE    print table to FILE (default: stdout)
	-s REGEXP, --sep REGEXP   use a custom column separator (default: whitespace)
	-F FPFMT, --float FPFMT   floating point number format (default: g)
	-f FMT, --format FMT      set output table format; supported formats:
							  plain, simple, grid, fancy_grid, pipe, orgtbl,
							  rst, mediawiki, html, latex, latex_raw,
