Subject: 29.0.50; vtable: Option to not draw the header line at all
Date: Sat, 23 Apr 2022 14:07:18 +0530

Hello Lars,

Thanks for the vtable library.  It is really handy.  I have one minor
feature request that would apply when using this library to insert
aligned rows of text without any specific column names i.e.,

    (with-current-buffer (get-buffer-create "*vtable*")
      (erase-buffer)
      (make-vtable
       :objects '(("Foo" "Bar")
                  ("Bar" "What"))
       :use-header-line nil)
      (view-buffer (current-buffer)))    

In this example, it would be nice if vtable did not draw an empty column
line when :use-header-line and :columns are nil, which would let the
library users to draw rows of aligned texts without resorting to a
workaround that sets header-line-format to nil afterwards.

P.S. shouldn't the default :face be variable-pitch-text instead?

Yup.  I've now changed it so that it doesn't create the header or header
line if columns aren't specified.

variable-pitch-text is for when you assume that variable-pitch will be
mixed with fixed-width, and that's not usually the case here.

Great, thanks.

Ah, I thought variable-pitch-text was for used for in-buffer text and
variable-pitch for things like the header-line and the mode-line
(usually things that don't need to be super readable or that important).
But now, I get the idea, thanks.
