## @code{width(@var{tbl})} returns the number of columns (variables) in the
## table, which is equivalent to @code{size(@var{tbl}, 2)}.
##
## @example
## @group
## tbl = table([1; 2; 3], [4; 5; 6], 'VariableNames', @{'A', 'B'@});
## w = width(tbl)
## @result{} w = 2
## @end group
## @end example

## @seealso{height, size, table}
## @end deftypefn

function w = width (tbl)
  if (nargin != 1)
    print_usage ();
  endif

  if (! istable (tbl))
    error ("width: input must be a table");
  endif

  ## Ensure Properties exist
  tbl = __ensure_properties__ (tbl);

  w = size (tbl, 2);
