…Python < 3.10 Before Python 3.10 (python/cpython#11270), formatting a string with a width of 0 fails: >>> f"{'foo':0}" Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: '=' alignment not allowed in string format specifier print_table() fails with this error if a column containing strings has width 0. Work around this for older Python versions. Signed-off-by: Omar Sandoval <osandov@osandov.com>
