If the text is scaled (using `text-scale-increase`) in a
`tabulated-list-mode` buffer, the text of the header is not scaled,
which leads to a messed up (row data doesn't align with header row) buffer.
text-scale-increase affects only the default face and faces that
inherit from it. It isn't supposed to affect any other face, such as
the mode-line, the header-line, etc.
Thx for mentioning header line. I've just noticed that
tabulated-list-mode supports using a header that doesn't rely on
`header-line-format`.
This feature (setq tabulated-list-use-header-line nil) also doesn't work
as expected. I can see that the header row is rescaled now when
`text-scale-increase` is called, but the row data still looks a bit
messed up (cols are not aligned) after calling `text-scale-increase`
multiple times. The issue can be easily seen by calling
`text-scale-increase` in the *Packages* buffer.
Maybe `tabulate-list-mode` calculates the positions of the beginning of
each column only once.
So you are actually asking for a new feature of the
tabulated-list-mode, whereby it defines "C-x +" etc. to produce effect
specific to that mode.
Yes it would be nice if text-scale-increase would properly rescale the
header-line, especially since (setq tabulated-list-use-header-line t) is
the default.
